Hi Jan,
I have two USRPs to test with, one a Rev 3 and one a Rev 4.1. Both
have the same behavior, except that one shows version 0.04 and the
other 0.02 when I first plug them in (in the system profiler). Then, I
run test_usrp_standard_tx, the firmware uploads, i.e. the LEDs start
to blink slower, but the system profiler still shows the old values,
i.e., they stay at "Vendor-specific".
I will try to see if I can enable some more debug information.
