I had USB issues with the tascam 1641 and it was caused by Windows Update....I went back to a previous version and it worked fine.

in my case it messed with the USB sockets and if I recall my 2.0 was suddenly called 1.1 or something and it stopped working...hmm, I dont recall all the details.
If your USB light was on before and stopped working later this might be it.
if it's not happening in the room, it ain't gonna happen on tape.-HG
