Dear all,

My USRP has been working great until recently. Today, I tried testing with
usrp_benchmark.py and got this, but not always. I tested it with gnuradio 3.1.3
and gnuradio 3.2.2 and got the same results.

Testing 2MB/sec... usrp_open_interface:usb_set_alt_interface: failed
could not set alt intf 0/0: Protocol error
open_nth_cmd_interface: open_cmd_interface failed
usrp: failed to load firmware /usr/local/share/usrp/rev4/std.ihx.
Traceback (most recent call last):
  File "usrp_benchmark_usb.py", line 106, in <module>
    main ()
  File "usrp_benchmark_usb.py", line 96, in main
    ok = run_test (rate, verbose)
  File "usrp_benchmark_usb.py", line 63, in run_test
    usrp_tx = usrp.sink_s (0, tx_interp)
  File "/usr/local/lib/python2.5/site-packages/gnuradio/usrp.py", line 232,
in __init__
    fpga_filename, firmware_filename)
  File "/usr/local/lib/python2.5/site-packages/gnuradio/usrp1.py", line 946,
in sink_s
    return _usrp1.sink_s(*args)
RuntimeError: can't open usrp1

The boards still blink, sometimes when I power it on it doesn't blink,
sometimes after a while both leds are steady. 

I would appreciate any hints to find out if I accidentally damage it.
