USB Devices Randomly Not Recognized - Windows 8 Only
Jan 23, 2013
On Windows 8, from time to time, all of my USB devices suddenly stop working, and the systray notifies that my "USB devices are not recognized." A reboot rectifies the problem, but the problem happens about once or twice a week.
Just a few weeks prior I had all of my USB devices going to a powered hub, which then was plugged into my computer. I happened to change motherboards from a Biostar 770E to an Asus M5A97 R2.0, which has plenty of USB ports. I hadn't bothered to eliminate the hub yet, and just as with the old motherboard, this one exhibited the "device not recognized" error. Ah ha, I thought! My USB hub has gone south.
So I threw it in the garbage, and plugged all of my USB devices directly into the motherboard (USB 3.0 portable drive, Logitech M705 wireless mouse, Belkin Wireless adapter, printer, and Remote Wonder. So I was quite surprised today when my USB devices dumped out, and Windows messaged me that my "USB devices are not recognized." I should note that I have installed AMD chipset drivers from the Asus website, as the board was quite unstable without them. With the Biostar, I opted not to install third party chipset drivers and it ran fine without them.

I was watching a TV show in my headphones, plugged it out for about an hour, plugged it back in during which time my Dell Inspiron 15 would have gone to sleep about 4 times.. I plug it back in after an hour and the music plays through the speakers and I looked up all solutions. None of them work. Checked my audio drives, disabled the speakers and enabled them back.. It is just a week old, my laptop.

My friend happened to look in Devices and Printers, and in the Multimedia Devices section he had about 10 devices showing up that he never heard of. Six of them were computers with names that he had never heard of, the others were devices that we could not tell what they were.
I expect that these entries mean that at some time they were on the same network that he was on. Would that be correct?
If so, then it is a matter for concern because he never goes on public networks. He only goes on his network at home, and a network in a small office that he rents and shares with one other person. They have their own router with security set up on it, and that router is connected to an Ethernet jack that most likely goes to a switch on a network that also provides internet service to some other offices in the same building.
This computer is only about 2 months old, so these entries can't be too old.
When I looked at his computer, he was on his home network and all those other devices showed as Offline. I right clicked on them all and removed them. Would it be a good guess that perhaps the security of the network at his office was compromised, and those devices were connected to that network at some point?
I told him to monitor and see when they reappear, but he won't be back in that office for 2 weeks.

I have a tablet that I installed Windows 8 Pro on.
Actually, I have installed Windows 8 Pro on 2 of these same tablets with the same problem.
They both have bluetooth and the bluetooth is on...and Windows 8 installs a driver for the bluetooth, but there is no bluetooth icon down by the clock in the systray.
From my understanding of Windows, if that bluetooth icon is not in the systray, something is not configuired right.
I can use a USB bluetooth dongle, and after it installs those drivers the bluetooth icon is present the systray. So, it likes the dongle. But, I don't know what the issue can be with the onboard bluetooth.

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.

All of a sudden I can't reliably play any video media on my Win 8 64bit computer -- was working fine yesterday and AFAIK nothing (other than perhaps Windows automatic updates) changed. My first thought was to try and restore but even though I'm sure I created a restore point it tells me there isn't one. Sigh.
Okay, so then I try to perform a reset (but keeping all my files) and it tells me some files are missing and to insert my recovery media. All well and good, I actually have that (and know where it is) but when I insert the disk it tells me it is NOT a recovery disk.
It is, of course, precisely that -- a Windows 8 Recovery Media for Windows 8 Products 64 bit. I am running an official copy of Win 8 (well, 8.1, but I have no media for that since it was a free update). Yes, it's OEM (Dell) but that shouldn't make a difference. And, more importantly, what I am to do now?

Windows 8.1, Broadcom 802.11n network card&driver,
My computer stopped recognizing the wireless networks at my university - oddly enough, some other networks elsewhere can be found (although I cannot test if I can actually connect to them, since they are passworded/not mine).
I followed the 3 steps of Network Posting Tips
Xirrus Wi-Fi Inspector showed nothing: Connection - Broadcom 802.11n network card - NA, everything under Wireless and Addresses also NA. No networks.
My home adsl modem works.

Have finished upgrading to Windows 8.1 and my RAID-5 ReFS volume has NOT yet been recognized. It was not available in "This PC" after the upgrade... and was still not available after using the ReFS registry hack. After applying the hack and restarting the computer, the only change was the System Reserved portion of my C drive became visible.
Under Administrative Tools> Computer Management> Disk Management, the drives in question are visible as a single RAID-5 volume but Status shows "failed", the file system entry is empty, and the drive letter is absent showing a red "x" icon.
Currently downloading the latest chipset, SATA AHCI, and graphics drivers for my mobo. Will update once those have been installed.

Everything was ok with sound but now the computer doesn't detect any sound devices like amplifier, headphones, speakers, etc. The computer does find the audio card, but not devices.

I just updated to windows 8.1 yesterday all is good, today I receive a update for Advanced Micro Devices graphics adaptor WWDM1.2 AMD Radeon HD 75209. It failed came back as error 80070103 says trying to install a driver that's already installed or a driver of less compatible . So I looked in add and remove I do see a advanced micro device but I don't know if it's the same or better how do I find out. I also googled it and read that it's never advised to update drivers threw windows update, go directly to the makers web site so how did this happen and what should I do?

I have recently built a new computer and installed Windows 8. All was running fine (including USB devices such as iPhone, flash drive etc), however since upgrading to Windows 8.1, none of my USB devices are showing up at all. Oddly, the mouse and keyboard still work.
When I go into the BIOS, all my devices (iPhone, Flash drive, keyboard and mouse etc) all show up in there, so I'm guessing it's a driver/Windows 8.1 issue that I'm missing?
I have been to the ASUS website and downloaded all the drivers I can find, but still no luck.
My motherboard is an "Asus Z97 Pro". I have tried contacting Asus support, but they are completely useless!

Windows 8.1 on Acer 5920G (WiFi adapter and more devices can't run)
After installation Windows 8.1 on my (ok old) laptop all seems normal but after reboot no WiFi, no Internet, no working WiFi adapter (the device can't start).
In device manager, wifi card (try 2 different intel cards Intel WiFi Link 4965AGN and Centrino Advanced-N 6250 AGN) can't start to work.
In the device manager 2-3 more unknown devices (yellow mark, no drivers or can't start work) but without Internet i can't try to fix this problems (2 pci devices and this one intel communication device).
I try all the known ways to add drivers (setup, manual....no internet) or to make it work but nothing, the devices don't works, can't start works (error code 10, i think).
So what can i do? NO windows 8.1 on my laptop? Now back to Windows 8.
My laptop Acer Aspire 5920G | CPU: T9500 (max 2800MHz) | VGA: Nvidia 9600M GT (512Mb) | RAM: 4GB | HDD: Seagate Momentus XT Hybrid 500GB (SSD/HDD 7200 RPM) | OS: Windows 8 Pro wmc 64bit

After upgrading to 8.1 all of my previously listed devices are no longer listed under devices... in fact there are no devices listed. I can also not add a device. If I look in device manager they are listed there and if I go to print the printer shows up and I can print. The screenshot below shows what I see when I open "Devices and Printers" in control panel. The biggest issue is not being able to add devices like Bluetooth speaker.

I'm a new Windows 8.1 user. Over the past two days two separate unknown network devices have appeared under 'This PC' in Windows Explorer (see screenshot below for the current one, along with its properties window). It appears people are able to access this computer - so a big problem!
As far as I can tell, all my security settings are in place (password on wireless network, all sharing disabled in Network and Sharing Centre, Windows Firewall is active, Windows Media Sharing is off).
How to close what I assume is a security loophole?

I have run into a problem with my Windows 8 computer once in a while, it's that my PC doesn't recognize USB ported devices as supposed to, but it does recognize things such as a wireless mouse and keyboard. Now, my question is, can I buy a wired Xbox 360 controller and connect it to my computer, and trust it to download the drivers correctly, and work like it's supposed to? I have got a new game, and really want the controller to work for it.

I have been several problems for a while since I installed Windows 8.
Firstly my screen and WiFi randomly stop working (at different times).
The screen goes blank (black) and it won't do anything (even caps lock) so I think it's completely frozen. Usually I hard reset, but today I got distracted and it eventually came back. No event logs or anything.
With the wifi, it says it can't detect any networks (red cross icon) and again the only fix is a hard reset, reinstalling drivers doesn't work.
Finally, recently my fingerprint scanner wouldn't let me log in. It says in biometric devices that it's unavailable, but none of the explanations applicable. I tried deleting my metrics and reinstalling but nothing...
I have an HP pavilion tx2 1250ea but I had to replace the motherboard and it's a 1050 or something, but obviously it's compatible.

After I upgraded my windows 7 to windows 8 pro I had this problem . There are four devices that have a yellow exclamation mark showing in the Device manager.
They are WAN Miniport (IKEv2 / L2TP/PPTP/SSTP)
All of them show this error: This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)
I don not know what these devices do or how to fix it .. I have also problem in Merto apps they cannot connect to the internet even though I can browse and download .. I do not know if those WAN Miniport devices cause this problem.

I am trying to use PS Media Server with Windows 8.1, but honestly whatever app I am using is irrelevant. The problem is, when I try to connect my PS3 to PS3 Media Server, it seems to require me to go into the right side menu, click settings, then change PC settings, then click network and then under connections, click my network connection and turn on "Find Devices and Content".
However, as you can see from my screen shot, that option is missing.
I am on my PERSONAL laptop, connected to a private network (it doesn't matter if I use my wireless or wired connection direct to the router it doesn't show up either way). I have tried enabling and leaving a homegroup, neither of which works.

I just recently bought a new HTPC server and installed Windows 8.1 on it. Everything seems to work great except my USB mouse and keyboard. The range of these wireless devices dropped to just about one meter. They work further away if I lift them high in the air but from waist level they only work from very close ranges. Before they used to work perfectly from distances up to 5 meters.
What's odd is that the USB recievers are in the exact same spots as they were in my old computer. I have an extender cable and a hub so there are no obstacles between the recievers and the devices. I'm not sure whether this is because of Windows 8 or because of the new hardware. My previous computer was a laptop running Win7 but the new one is a desktop. The devices seemed to work bad even in BIOS so I suspect it's the hardware.
I have installed latest drivers, replaced batteries and tried different positions for the recievers but nothing seems to fix this issue. I have not added any new wireless devices in the household.

At first I thought maybe it was the one movie(battleship), but after subsequent testing with different dvd movies, I have to ask, is it normal for the dvd drive to sometimes not recognize theres a disc loaded?
I've got cyberlink power dvd 9.0, which has a dvd movie playback codec.. so its not a software issue.
I've also got vlc media player which comes with a dvd movie playback codec, so again, not a software issue
Could this be my drive showing signs of premature impending failure on a machine just under a year old? or is this windows stuffing up and not recognizing theres a disc loaded?

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?

My laptop automatically updated to Windows 8.1 and now my HP wireless printer is not recognized.
Even if I plug it in to the USB port, it's like it won't even find the printer. I don't even hear the sound that the printer is plugging in. I have tried several USB ports and yes, the ports are working as I have tried other hardware in them.

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.

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?

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 win8 in a public environment as a kiosk and users are exporting data via the usb.
