USB device not recognized The last USB device you connected to this computer malfunctioned, and Windows does not recognize it. This error persisted through 2 fresh installs, even though the device manager shows all of my USB devices as functioning at all times. In fact, the issue persists when there are NO USB devices connected to the computer at all.
However, I do see an entry under the 'Universal Serial Bus controllers' tab with a yellow! Triangle, with a description of 'Unknown USB Device (Device Descriptor Request Failed)' I am unable to update drivers for this mystery device, and disabling it does not stop it from popping up every 2 seconds. I have attempted to update the drivers for all devices under this tab (ASMedia USB 3.1, Intel USB 3.0, USB Composite Devices, USB Root Hubs) but nothing is helping. PLEASE, any help would be great. I really don't want to tear this apart and swap out the motherboard. The case was a real pain in the neck to work with.
System specs: MSI Z170A Gaming M5 Intel Core i7-6700k eVGA GeForce GTX 1080 FTW G Skills Ripjaw PC4-17000 (2x16GB) Intel 600p series m.2 256GB (Primary hard disk). I had the same 'USB not recognised' message pop up regularly a while back. At the time I had no USB devices plugged in, but I did have a USB charging lead connected to a 'dumb' device (no intelligence whatsoever, just charging its battery). This battery had charged without problem for months before that, but shortly after the messages started to appear the charging failed. Both problems were solved with a replacement charging lead, though that too failed with the same symptoms about 6 months later. The current (newer and a different brand) charging lead has no such problem. So, seems like a faulty USB lead can (possibly by allowing two of the connections to make contact when they shouldn't) lead to Windows incorrectly detecting a phantom device.
Maybe you have a faulty USB socket and/or lead? Or some dirt has got into the socket and is bridging across two of the connections?
