I running the latest gnuradio from git and see these messages when I

[balister@moose gnuradio]$ usrper load_standard_bits
usrper: found unconfigured usrp; needs firmware.

Which version of libusb are you using?

Looks like libusb-0.1.12 (-21.fc11.x86_64)

The kernel is throwing -EPROTO, which, generally, is indicative of a
low-level error with the HCI code. Can you try a different cable /
usrp combination? I can’t reproduce this error on any of my machines.

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.

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.

Disregard my chatter, replacing the power supply has resolved the
problem.

Ive got Two USRP 1 kits. Both of them were working fine but suddenly
both are not powering on.
