Hardware Drivers :: Flash Drive Not Recognized In One PCs USB 3.0 Ports
Sep 15, 2014
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.

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.

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)

I have already uninstalled and reinstalled and rebooted many, many times. These are my current registry entries:

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.

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..

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 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).

My usb is apparently disk write protected. there is no physical switch on the usb. i can't understand it as it was working perfectly one day & the next it was write protected, it maybe to do with the fact that i formatted with 'wii backup manager' allowing me to put downloaded wii games onto the usb & play it on the wii, but i can't remember if i done this or not.
I googled the question and someone said to run cmd, diskpart, list disk, select disk X, attribute disk clear readonly, clean. it goes on for a few more steps but at this point i get the error message "DiskPart has encountered an error: The request could not be performed because of an I/O Device error. See the system event log for more information"
What can i do. the usb is only around a year old so shouldnt be damaged already.

When I try to format my flash drive it shows that the drive is Write-Protected. When I tried to remove it through diskpart it said it completed successfully, but when I try to format it again it still didn't work. I also tried removing it using REGEDIT with storage device policies, but that STILL didn't work.

The issue is finding the file location for my flash drive. My computer only has 3 external USB ports. I have tried all of them, when the flash drive is plugged in somewhere on my computer it should indicate another drive location. I can't find anything....not sure where to look or if I'm looking in the right place. All that shows is c: drive & E: drive. The E: drive is exclusive for the OS system restore (can't be used; not accessible for anything else). The only other is the DVD drive. Nowhere can I find evidence of the flash drive plugged into the USB.
I have all the essential drivers & everything is up to date [I have a task scheduler & Driver updater software installed. All drivers are up to date. This is a new computer, only 2 months old].
I have gone into device manager & checked all the USB & composite serial bus controllers to make sure they are powered on (my computer has an energy saving management thing & it will possibly deactivate the hubs when not in use). According to the power management settings they are not set to "sleep" but all ports are active. I can't figure out why I can't find my drive, nothing is appearing when I have the flash drive plugged in.

Yet another lovely problem with 8.1. When I plug in my drive, it shows up in with all of my other drives, and when I double click it to open it, the explorer window freezes, and doesn't unfreeze until I unplug the flash drive. I don't know what went wrong. Maybe it is a driver issue? I am positive that the drive is fine, because it works on my laptop, and even works on this computer in a linux virtual machine.

It is a 64 GB Toshiba USB drive (TNU). Problem is that every time I try to format to NTFS the normal way with Windows 7 or Windows 8 I get the message: Windows was unable to complete the format.
I tried to format it using the specific software from the drive manufacturer, TNA.
A friend managed to format it to FAT32, but the next time I tried to access the drive Windows showed a message saying that I needed to format the drive to use it. Then there appeared only the exFAT option.
I also tried some partition software, like AOMEI Partition Assistant Standard Edition, and it could format to both FAT32 and NTFS, but when I removed and put the USB drive back Windows again warned me about the need to format and again I had only the exFAT option left.

I have 3 disks in my computer, of which 2 are SSDs.
I swapped the SATA ports between one SSD and the HDD so as to give the SSD a SATA port with maximum 6gb/s transfer speed, and now the access to the HDD is denied. The drive letters are correct, as they should be.
The user (myself, admin) did not change.
What can be done about it? I already tried to check the ownership of the drive and says STEVECOMPUTER/Administrators, which looks good, as my user account is an admin. Still, I have no access.

my USB 3.0 ports are not working with my USB 3.0 ext-HDD. It's an ADATA Nobility NH13 I don't have any other USB 3.0 equipment to test, but the ext-HDD works perfectly on my laptop and on my TV as well, so it's definitely not the HDDs fault.
When I plug in USB 2 devices, they work perfectly and at maximum speeds. Even the HDD does work when connected with a USB 2.0 cable instead of it's own 3.0 cable.
This behaviour is present on front as well as the rear ports.
In the Device Manager there IS a USB3.0 driver:
Intel(r) USB 3.0 eXtensible Host Controller - 0100 (Microsoft)
Universal Serial Bus controllers
Generic USB xHCI Host Controller
PCI but 0, device 20, function 0
This device is working properly
Hardware IDs:
PCIVEN_8086&DEV_8C31&SUBSYS_50071458&REV_04
PCIVEN_8086&DEV_8C31&SUBSYS_50071458
PCIVEN_8086&DEV_8C31&CC_0C0330
PCIVEN_8086&DEV_8C31&CC_0C03
P.S. The specs are all up to date, so feel free to check them out.
P.P.S. In case you are that lazy, I am running Windows 8 Enterprise x64, and Gigabyte GA-Z87-HD3 motherboard

I have a strange issue that started appearing when I installed win 8, all my USB ports seem to reset with no apparent reason on different time periods, from a few minutes to hours, its like I unplugged the thing that's in the usb, and put it back in, its really annoying since my wirelles is via usb so I loose my connection every time it happens, its not I hardware problem because when I switch to win 7 it runs perfect
I have checked the drivers for the usb and it says its up to date?

I don't know why but my external hard drive isn't showing up when connected.. Windows makes the connection noise when I plug it in but it don't show up in disk management, device manager or anywhere else... If I plug it into a regular usb port it works fine... And its a usb 3.0 capable drive it worked before....?" I tried the new hardware wizard in device manager and didn't see anything... drivers all look fine....

I have problem that just crept up, my rear usb ports are malfunctioning. when I plug my mouse in the light underneath it comes on, but the mouse is not operational. The keyboards numlock light doesn't even go on.
My front ports are working now, but this is greatly inconveniencing me because, my scanner, printer, and headphones were plugged into there and now I have access to neither.
This started as soon as I plugged my phone into the front usb port as I have done over a thousand times with multiple phones even of dubious origin with no such a result.

I have two programs on my hard drive. They both require access to a COM port. When I attempt to access either one it works fine, but I need to have both of them running at the same time---thus I need an additional COM port. When I setup either program, the available port appears (COM 3). It does not allow the entry of any other port or call up an additional one---with all the COM's available, it would seem reasonable to be able to use more than one port at the time! I am using a Dell Pentium Laptop (1545) with Windows 8.1 PRO. The computer has 3G of memory.

My usb ports do not recognize some devices. Sometimes when I plug one device another one is unplugged., some times a specific usb port works, sometimes it doesn't. eg: when i unplug the mouse nw and plug it again it will stop working. if i plug another device eon a different usb port the mouse is disconnected. I went to control panel devices Manger and uninstalled every usb port and enable it again with no results.

I have several printers at work all hooked up to a samba share so that the whole office can use them. We have Konica Minolta, HP and Lexmarks predominantly but some other brands as well like Kyocera.
I have a fresh Win 8.1 Pro install and i have installed the printer drivers via the Windows update mechanism for all the printers. Some i've added via the samba share some via direct ip connection.
For whatever reason i cannot add/delete or config any of the printer ports as seen in the attached screen cap. I've even tried the windows Administrator account to no avail. UAC is off and i have admin rights to the pc.
I have sought support on freenode's #windows channel and googled the hell out of this topic, to avail.
I cannot replicate the issue in Win 7.

I have a new PC that a friend built for me, I've noticed that the wireless receivers for my keyboard, mouse and wifi aren't working properly when plugged into any USB ports (front or back, 2.0 or 3.0). The range for the keyboard/mouse is awful and wifi connection is very slow if it connects at all.
However, all peripherals work correctly when plugged into a powered USB hub, the range for keyboard/mouse is huge and internet/download speed is fantastic.
Everything is up to date and was installed correctly. Having a couple of forums and speaking to Asus, I think it's a power issue. I arranged an RMA but the problem persists with the new motherboard.
Mouse - Microsoft Wireless Mouse 4000
Keyboard - Logitich K400R
Wifi - Edimax EW-7811UN
OS - Windows 8.1
Case - Bitfenix Prodigy-M
PSU - Corsair CX500
Mobo - Asus H81M-Plus
CPU - Intel Core i5-4440 3.10GHz
RAM - Corsair Vengeance 8GB (2x4) DDR3 1600
HDD - Seagate Barracuda 1TB
GPU - MSI R6850

I am having problems with USB 3 devices disconnecting and reconnecting all the time when they are plugged into the Esata ports on the back of the motherboard in my sig. The USB 3 devices work ok in the normal USB 2 and 3 ports on the motherboard but I am not sure why they are not working in the Esata ports? I'm running Windows 8.1 with all the latest drivers and I am also running the BIOS f7e provided by Gigabyte to see if this would resolve the issue but it's not worked. If I connect USB 2 devices to the Esata ports they work ok, but could they possibly be faulty as they are not working correctly with USB3 devices?

And it happens only when I boot the computer up and find that neither my keyboard or mouse are working then I plug them into front (2) avaialable usb ports and they work fine....
And then If I try to uninstall universal bus controllers by device manager then my keyboard + mouse stops working (obviously) then I shutdown via power button .... plug keyboard+mouse again back to rear usb ports... and they start working till few days...
I'm on windows 8.1 x64 with latest updates and all latest drivers etc...
The funny thing is this problem is with me since last 2 years or so... and I changed 3 Power supplies since then and luckily one motherboard, changed 3 mouses and 1 keyboard, 1 Hard disk too
even if they are plugged in rear ports I get "USB Disconnection" sound sometimes....
now thinking about buying a bluetooth keyboard + mouse but there are other things that needed to be plug in into rear ports... or should I go for an internal USB 2.0 PCI card ?

I have recently bough a new PC. Now that everything is put together and installed I am facing only ONE problem.
I own an Adata Nobility NH13 External HDD which is USB 3.0. When I plug it into any USB3.0 port using a USB3.0 cable, the drive does not show up in My Computer, nor in Device manager, regardless if I use the Front or Rear USB3.0 ports.
The USB2 ports work just fine with it but what is the point in having a USB3.0 device if you don't use it the way you should ... If I plug in USB2 devices in the USB3.0 ports the work great, and even if I connect the ExtHDD with a USB2 cable it does work.
Now, the first thing you would think is that the USB3.0 drivers are missing but in the Device manager, unser USB controllers, there is a Intel(R) USB 3.0 eXtensible Host Controller-0100(Microsoft).

I'm in the process of moving to an SSD and need to create a backup drive in order to repair the BIOS after transferring everything. However, when I try to create one - the create a recovery drive program won't recognize the flash drive I have connected as a flash drive.
I first tried with a SanDisk Cruzer which apparently had a quirk in that it shows up as a hard drive instead of removable flash drive. That seems to be well documented on forums all over the place and there is no fix.
So, I purchased a cheap 8 GB stick (no brand) and Windows (I'm running 8.1 x64) recognizes it as a removable disk. However, the create a backup utility still won't recognize it. I've found some random fixes that have worked for some (such as plugging it into a different USB port) but nothing has worked for me so far. I've tried doing it with the "copy the recovery partition" option both checked and unchecked.
If there's no solution to this wonderful "quirk" of Windows, then is there something else I can do to repair BIOS? Seems like there's not a fix to my problem out there...
EDIT So as of right now, I tried using HPs recovery software which seems to do the same thing as copying over your entire recovery partition. That didn't work either. However..when I had both USB sticks plugged in the Windows supplied utility recognized the SanDisk Cruzer when I checked the "copy the partition" thing

My Acer Aspire A7600U-UR24 came with windows 8. I made a recovery drive by choosing "create recovery drive" in windows 8. After making the drive i installed windows 8.1 from DVD. Some time later I tried to restore it back to factory with my recovery usb. Every time I try I get "windows cannot find a system image on this computer" even though my flash drive is plugged in. I tried booting from the drive, doesn't seem to work. Not sure if my windows 8.1 version not being activated has anything to do with it (I installed 8.1 on 2 computers from the same dvd didn't realize i couldn't do that) . but I think I should still be able to boot from the drive.I was thinking if the problem is my flash drive, can I somehow transfer the system image from one flash drive to another?
