Now it works fine, but when I try uhd_usrp_probe this is the result:

Did you actually have an external clock connected?


So, when you do the uhd_usrp_probe, add "clock_source=internal" to the device args -- it looks from this trace that it's trying to use an external clock by default.
  Which it shouldn't.
