I get this message randomly, even without connecting any USB device.
I started getting this message in December of last year, after that I got my system reinsatalled a few times. In between I had a hard disk replacement also.Earlier I also had the BSOD error saying USB BUG CODE DRIVER
. After the replacement of hard disk frequecy BSOD error has greatly reduced, once or twice in a month.Thats ok, my main concern is the USB DEVICE UNRECOGNISED error.I have a USB ddevice (avrisp mkII programmer) which is malfunctioning and I think this could be the cause.
This is what I get upon clicking the error ballon.
