What's happening is that the kernel is throwing an EPROTO error on
certain control transfers. The error code passes through libusb and
the USRP driver simply reports the error. Unfortunately, the error is
vague and non-specific, though it often indicates a line or hardware
issue. I've heard this happen a few times with the USRP. One case was
a faulty power supply and another involved a USB webcam.

So if I understand correctly, your previously working USRP fails on
both machines now?
