Another question ... It sounds like my USRP power supply is emitting a high pitched whine. Is this normal? Unloaded I looked on a scope and see 6 volts plus spikes above that about a couple of volts in magnitude.

Can you try a different cable / usrp combination? I can't reproduce this error on any of my machines.I tried a different cable and from my beagle board (running libusb1). I am beginning to worry about my USRP. Time to borrow one and see if my USRP has gone flaky.
