USRP2 UHD error: No control response

I just successfully (I think!) installed UHD and gnuradio, and have
installed the firmware provided by Ettus for UHD installs newer than
August 2010. I can successfully find my USRP2 using uhd_find_devices,
but running uhd_usrp_probe or any python script using UHD drivers
results in the error

Error: no control response

I found a couple other threads from the past dealing with similar
issues but couldn’t find anything in them that I could use to
troubleshoot my situation.

I did notice that after flashing both firmware and fpga binaries on
the SD card that instead of just D and F LEDs being lit up, B is also
lit.

FWIW, I’m on Ubuntu 10.04.

Thats not good. The find_devices app does the bare minimum to discover
devices, where the probe app does that and more. Seems like something
further down the line might be at fault.

Can you tell me the following:

Git hash of your uhd install.

Which images you loaded on the sd card.
