Hardware Drivers :: USB Hub - USB Device Not Recognized?
Jun 10, 2014
I recently bought a cheap USB Hub off eBay. I plugged it in and connected my devices and it always works.
However, about 75% of the time when Win 8 boots, I get about a dozen "USB connect/disconnect" sounds and a window that says "USB Device not recognized". (sometimes 3 or 4 of these windows)
I've searched for this issue but every post that I find provides a recommendation for a USB device that is not working. None of these suggestions applies because after all the boot noise, the hub and it's devices work. It just seems like Win 8 is having trouble recognizing the Hub but keeps trying and eventually succeeds.
The Hub is plugged into a USB 2 port with a scroll wheel mouse and a Dymo LabelWriter 400 connected to the hub.
Win 8.1 Pro X64
Asus CM3870
Intel Core i7-3770
16GB RAM

Recently my "PS to PC Converter" USB device, as shown in image was not recognized by my laptop. It was working fine as of yesterday, where I was playing FIFA with my friend. Then today when I plug it in, it says USB device not recognized even though I can still on the analog but the controller is not detected by the game. Other games that I use to play with controllers are also not detecting the device. I kept reinstalling the driver but still the same message. Restarting computer, turning it off for a few minutes did not solve my problem too. I'm pretty sure my USB ports are fine as my mouse, keyboard and hard drives are working in all of the USB ports.
EDIT: I check the Device Manager and found a yellow exclamation mark on Other Devices named "Unknown device", I check the properties and says Code 43 on the status. I Enable/Disable it, still the same message.

I have a flash drive that I previously used in public computer lab (where many viruses linger) the other day to do my work. As I got home, the flash drive isn't working anymore, saying "USB Device not Recognized". I also noticed that it really took me a while to finally, safely remove it from the computer lab's PC. So I actually wonder if it actually removed my flash drive properly.
On Device Manager, it says "Unknown USB Device (Device Descriptor Request Failed)".On the Properties, the device status says "Windows has stopped this device because it has reported problems. (Code 43) -- A request for the USB device descriptor failed."
My flash drive is a Kingston Flash Drive DataTraveler (DT100) 16GB, and my PC is running on Windows 8.1.
Things I have tried:
- Shut down my PC, unplugged power and removed battery, waited for a while, booted my PC and try plugging in again.
- On Device Manager, uninstalled it and scanned for hardware changes, it still returns as "Unknown USB Device".
- On Device Manager, I clicked "Update Driver Software..." and it returns me a message saying "The best driver software for your device is already installed".
- Unfortunately, when I visited Kingston's website to check if there is driver for this specific flash drive, there isn't any... "There are no downloads or drivers available for this product".
- Used Windows 8's Troubleshooting tool. It only detected my problem, but was unable to fix it.
- I also tried plugging it to other devices that are running on Windows XP, Vista and 7, none does any better.

I am using Inspiron 1545 which has Dell Wireless 365 Bluetooth Module which is of broadcom. When I try to install driver compatibility issue comes up. It doesnt proceed even though i have marked compatibility as windows 7 or vista too.
I have tried using the broadcom tool to detect the device and install the driver but that also fails to detect the module.
And when i use my second OS windows 7 bluetooth works flawlessly. So its only windows 8 not able to detect my hardware. I have also checked in device manager and there also it is not present.

Last part of the message, (Device Descriptor Request Failed). I get this, in Device Manager, and I have searched for an answer on the net. Also it is a Code 43. I went through my laptop, with an HP Technician this morning, I might add at a cost of 5p/minute, for 30 odd minutes. He has said that because I had gone over to Windows 8.1 and the recovery discs I made will not load, to put back in Windows 8. I have to send the laptop back for re-installing the OS, because Windows 8.1 do not have the update for my problem. Also the R.H. USB socket has a failure ID:0GAPTK-6T7716-MFPWWK-8D1Q03. I personally think that this is all what the problem is. a duff USB. Is this a cop-out???
Does Windows 8.1 having driver WHQL problems?
I only found out the problem with the usb when I tried to download a Mobi file to a Kindle for my wife. The other usb's work OK.

My Seagate GoFlex 500 isn't showing up in Windows. Disk Management sees it, but there's no feasible option there. It's not a blank drive, so I can't make a new simple volume, only delete it.
I have important data on there. What gives?

Over the past three weeks or so, there have been probably seven times my wireless USB Nexus Silent Mouse has not been recognized on cold computer startups (usually morning). Windows 8 (Pro x64) throws up a message that a USB device wasn't recognized, and I don't see a mouse cursor. Unplugging and replugging the USB mouse's stick, which is in a port on the front of the computer, solves it. The mouse driver is up to date, changing USB ports hasn't made a difference and the batteries are fine (and have been changed).

I have a TSST 208DN DVD drive installed in a Win 8 Pro Toshiba C855 machine. I am no longer able to use the drive.
The problem began with my always having to reinstall the drivers upon reboot. I found a solution, or so I thought, that advised me to delete my upper and lower filters entries in the registry. I only had an LowerFilters entry for AnyDVD. I deleted it and can no longer use the drive.
Dev Mgr shows drive with yellow excl. triangle (see image #1 below) and this msg under the general tab of properties - Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19) (see image #2 below). I have drivers from MS and Toshiba installed (see image #3 below)
image #1
image #2
image #3
I have already uninstalled and reinstalled and rebooted many, many times. These are my current registry entries:
image#4
I have uninstalled and reinstalled AnyDVD. I have put back in the LowerFilters key and deleted it and rebooted many, many times. The registry entries look like those on my other laptop with the exception of lowerfilters set to AnyDVD and upperfilters set to the manufacturer's driver (GEARaspiWDM) and that machine works just fine - for about 10 minutes and then overheats and shuts down - it's a Dell - but that's another story.

When i power on computer, my usb flash drive isn't recognized right away. I need to re-plug the flash drive every time, when i power on computer, then it's recognized normally.
It's not such a big problem, but I have this usb flash drive always plugged at computer back side.

In the process of installing a new Win 8.1 machine, going mostly OK, but I have a WD Passport Ultra that is not working with it at all. I plug it in, it lights up and spins, but never shows up as a drive either in "This PC" or in disk management; nothing at all in device manager either. I would have said defective unit, but it works perfectly on all my other installs including Vista, 7, 8.0 and even a Mac! Don't know what to do here, I can certainly access the files on another machine and transfer, but I would like to use this drive with the new machine...

Few days ago I bought a new Lenovo Thinkpad Edge E540. It has two USB3.0 ports and one USB2.0. I bought the machine without OS and installed Windows 8.1 Pro(x64) myself. Everything seems to be working fine except when I want to use My WD Elements 1TB external HDD in USB 3.0 port. It just doesn't get recognized. In USB 2.0 port it works fine.
What I've gathered and tried so far :
- Device manager does not show anything not even Unknown Device , yet my USB 3.0 Kingston pendrive works fine out of the box in the same slot
- I'm pretty sure the USB power is not the issue because the WD HDD , when plugged, starts blinking for a while , then lights up fulltime and i can feel and hear the drive spinning
- I've disabled USB selective suspend in my Power plan
- I've disabled Fast Startup
- In msconfig , im stuck at "Selective startup" (if changed it doesnt even let me APPLY and switches back to Selective right after I close/change tab in msconfig, I tried doing it in safe mode , same thing)
Using my harddrive in USB3.0 speed is essential for me.

So I have a WD external HD with all of my research data as well as some text books and other important things on there and for some reason I got an I/O error and after that the drive does not show on the computer anymore. The computer recognizes that there is a drive there and will read that it is a WD passport but cannot tell the size of the disk and will not register it as an external drive whose media I can explore and work with. What is wrong and how can I retrieve the data?

HP's support site for the specific model M6-1035 lists no driver for the webcam. it was there under windows 7 but I don't recall ever deliberately installing a driver for it - I assumed win7 had it.
Windows 8.1 does not. nothing in 'devices', nothing under device manager, and no driver listed on the HP support site. the latter is not surprising since they don't provide a host of drivers for the laptop.
No keyboard-specific drivers [like for the function keys etc], wrong firmware for optical, and other small things.
Any generic cam driver that will function?

When I switched to a Windows 8 laptop from my MacBook, my iPod Classic is not recognized by the Win 8 machine. I've tried to copy and paste music files from the HD to the iPod, but once the iPod is ejected, no music shows up on the iPod. I've downloaded iTunes, which seems to recognize when the iPod is plugged in, but I haven't been able to move any music from the HD to the iPod.

My portable hard drive stops showing up all of a sudden. It is connected to a USB hub. When I go to 'Disk Management' in 'Computer Management', the hard drive shows up as Unknown - Not Initialised. Also this hard drive works while not using the USB hub, and the USB hub works as well with other devices.

I built my computer a couple weeks ago and am running windows 8.1. I currently have a 128gb SSD and a 1tb internal hard drive (WD Caviar Blue) I obviously used the ssd to boot windows and currently windows is detecting my 1tb hard drive but it is not usable. I have tried diskpart commands to clean and format and I keep getting the error message "DiskPart has encountered an error: The request could not be performed because of an I/O device error". The hard drive was brand new and cables are fine. This is what everything looks like..

I have Silicon Power Blaze B20 flash drive, which is not recognized by my desktop PC's both USB 3.0 ports. The flash drive's light blinks when pugged in, but no reaction from PC's side. I have tried to plug cord between flash drive and PC, but no change. It does recognize the device when plugged in any other USB 2.0 port. And the device is being recognized by other computer's both USB 2.0 and USB 3.0 ports, so I assume it is PC's fault, but what it is. My PC's USB 3.0 ports do recognize any other USB 3.0 devices - my external HDD, other USB 3.0 devices but this drive.

I am running Win 8.1 Pro 64 bit. I have a WD "red" HDD connected externally in a NexStar-NX box. The NexStar supports USB 3.0 and eSATA. The USB 3.0 connection works fine and shows up in WIN 8.1 disk manager and all files are accessable. When I use a eSATA cable (have tried 2 different ones) the HDD is not recognized by Win 8.1. Win 7 HP 64 bit sees the eSATA connection and all works well. The HDD, when using the eSATA connection, shows up in the post boot screen as I have the HDD listed in the BIOS. I would like to use the eSATA connection as I'm short of USB 3.0 ports on my ASUS Maximus V Gene mob. Is this a Win 8.1 quirk?

Having problem with a USB drive constantly disappearing and not being recognized?
My current solution is to delete drivers in device manager then wait until they load again. This is a temporary solution. I am using a VivoTab ME400C tablet pc with full Windows 8 in a public environment as a kiosk and users are exporting data via the usb. I cannot ask people to constantly delete drivers before they try an export to a pen drive.

I am unsure whether I should enable "Automatically get device drivers, apps, and info for new devices" when installing Windows 8 Pro?
What exactly will it do?
If I enable this, will Windows then automatically install software packages/drivers from the manufacturer, like for example the Logitech Setpoint software for their keyboards and mouse and similar software for other devices? I don't want or need that. Or will it behave like in Windows 7?
On my other PC with Windows 7 I see in Windows Update that there are a couple of optional updates, including that Logitech stuff, as well as some driver for a BenQ monitor I have and also nvidia video drivers. This kind of stuff I don't want or need installed automatically as important updates in Windows Update - so I am worried if enabling this automatic driver stuff in Windows 8 is different than Windows 7? Meaning that it will get installed secretly/automatically?
However, it's fine that Windows finds them so I can manually go and check if I want to install any of it.
The key is that the updates are optional in Windows 7, but I have seen a few people complain about Windows 8 installing stuff like video drivers and mouse drivers automatically.

I've installed Microsoft Windows 8.1 Version 6.3.9600 Build 9600 on my HP 430 Notebook PC with 1 GB RAM and Pentium CPU @ 2GHz 2 Cores.
Display drivers are not working properly (i.e., everything appears bigger and unclear), earlier I'd successfully updated the display drivers and made it work using Device Manager. making a backup of the drivers (may be in .inf format) from the installed drivers so that I don't have to update it every time I re-install it.

I work at a hotel, and we are having issues with our public computer (Acer Aspire XC-603G desktop) connecting to the internet. As it seemed like an issue in the wall, I decided the easiest way to fix it would be to buy a wifi USB adapter (NETGEAR N300) and just use that instead. However, when I try to install the driver from the included CD, it keeps giving me an "access is denied" error.
The account I'm using says it has administrator privileges, though that's been giving me issues as well. The person who initially set up the computer only set up one account, which anyone could use. I added another, gave it the administrator rights, and removed them from the original. However, even though it says the new account is an administrator account, messages often pop up and say that I can't do what I'm trying to do because I only have standard privileges.

I connected a hard drive to my PC. I was able to read/write to it just fine. In fact, I've used it various times in the past. I just tried connecting it again now, and the drive is not showing up on Windows 8.1 at all. It's not being detected.
I connected the drive to a Mac to see if it was the drive, but it wasn't: the Mac was able to read it just fine.
I've had a similar situation in the past with this machine, where my iPhone was, seemingly out of nowhere, no longer recognized by the system. Plugging it in would register on the phone, but the PC wouldn't acknowledge its existence.
I'm completely at a loss as to why this can be. Other drives connect to the PC just fine (in fact, I have another one connected now, as I write this, backing up some data).

I'm running a custom build PC on which I clean installed a (legal) copy of Windows 8.1
My system works fine except it can not install drivers for ANYTHING non-standard. Keyboard, mouse, memory sticks, HDDs all work fine, however when I plug in my phone/tablet/camera etc via USB, it fails to install drivers and I can't use my device.
Here's what device manager looks like with my (android) phone plugged in
And when I select Update driver software, I get this error:

I have a newly home built MSI AM1i motherboard and have it running fine with Windows 8.1. I am trying to expand the number of SATA ports it has (comes with only 2). The mobo has a mini-PCIe card slot.
I purchased a AsMedia 106x, 2-port, mini-PCIe card (had to use a ribbon-cable extender to get it connected).
That all appears to be fine. I struggled a bit with drivers, but eventually found a Windows 7 AsMedia 106x driver set. Loaded that, seems ok.
Problem: When I go to device mgr, it does not see the added 2-ports. When I first boot up, during the black-screen phase, it does report that the AsMedia device is loading and will actually find/name a hard drive that I attach to one of the new ports. It then almost looks like it will load windows, give the nice little blue windows 8 flag and just sits there. I can hear a drive cycle every 2-3 seconds, but nothing.
I eventually have to hit the power button to shut down. If I disconnect the drive added to the new card, it will start up. The AsMedia device looks to load during a black-screen phase, but reports no device found, and then loads Win 8 Correctly. When I get in, again, no SATA ports shown for the new device.

I have the very latest Windows 8.1 update.
My internal multi card reader has been working fine for just under a year but just recently it has stopped recognising SD cards. When I insert a card it normally opens an explorer window but now it does nothing and does not show in file explorer.
Though if I click on .. file explorer/manage/disk management .. it then opens an explorer window for the card.
I have the setting in autoplay - memory card and removable drive set to open explorer.
I don't think the card reader is becoming faulty.

No USB device seems to be getting detected on my machine when I plug in a flash drive or an external hdd I get the distinctive sound from my speakers that an USB device is plugged in but nothing is showing up in "My Computer". I went through the event logs and found that Windows is failing to load the USB device (check image in attachment logs.jpeg). Recently I installed iTunes, so I though it might be causing this problem but I uninstalled it even then the problem persists. I don't want to format my machine just because of this small problem. Is this a driver conflict ? How do I find out why windows is all of a sudden failing to load the USB devices ? I have uploaded a copy of the saved logs detailing this failure(logs.zip).
