Usrp stopped working

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
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)

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.

Regards,


Reynaldo
