I forgot to mention that I have the RFX400 and RFX2400 daughterboards. I also tried the same thing with both daughterboards removed with the same result. Unfortunately I don't have the BasicRX/TX with me and can not test it. Do you have one of the RFX400 or 2400 with which you could test?

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.
