I re-installed my machine twice over the past 7 days and both times I am left with a very annoying pop up which says "Unknown USB device - one of the devices attached to your computer has malfunctioned". This pop up can happen literally as often as 20 times a minute.
I have re-installed this exact PC probably 5 times in 2 years and never had a problem until this week's re-installs. There is no new USB hardware attached, just three basic things I've always had (webcam, USB printer, scanner). Even with ALL usb devices disconnected I still get this message. The only way I've been able to disable this pop up permanently is to disable my USB root hub in device manager. That obviously takes away my USB ports and is not much good in the long run.
I've read through your forums, and most people with this problem seem to be able to get it to identify with a particular device. In my situation, I cannot imagine what device could be causing this annoying error.
Is there any way to just disable this pop up service? My computer is running fine, all USB ports work. I have tried to detect this unknown device for almost a week and I have read a tonne of forums and help places and have had no luck. I'm just left completely clueless. Even if I disable the unknown device, it STILL pops up.
Thanks btk1w1, that's the kind of fix I've been looking for. I just tried it, so far so good, so we'll see how it goes.
Ideally, i'd obviously like to identify this unknown device, but since that seems impossible at this point, getting rid of the nag is the next best option, since all my USB ports still work.
The ONLY change that has been made to my PC since re-installing without problems the last time, was I added a 2nd SATA HDD. I don't know if that can somehow relate to a USB error, but that's the only change I can think of. I've been thinking maybe my USB setup is starting to fail? But all the ports work.
Anyways, pop up is now gone, unfortunately, that probably means I'll miss the odd pop up I'd like to see But better than what it was.
The only thing that I can think of is that you might need to update your chipset drivers, there may have been a MS update since previous OS installs that causes this error.
A SATA HDD addition shouldn't cause this error, but it wouldn't surprise me if it has.
In any case go to your motherboard manufacturers website and have a look if there is a later chipset driver release than the one you are currently using.
If you need a utility to correctly identify the exact motherboard (make, model and version) you currently have SIW should do the job for you. It has been very good to me in the past.
Click on the download button at the top of the page, and on the new page on the left has the freeware versions. I like the standalone version because I take it on my flashdrive with me and can use it on any pc... but the one with the installer will suffice also.
