[USRP-users] USRP2 + XCVR2450 configuration

Hi,

I'm quite new to the SDR world. I started with an USRP2 (r4) +
XCVR2450 dboard. I tried some examples with gnuradio, but I'm still
not sure, if everything is setup correctly (mostly it seems I'm only
getting noise)..

For start, I don't think I should get this output (no sign that my
daughterboard is recognized correctly) for uhd_usrp_probe (check down
below).

Do I miss some installation/configuration steps?

Thanks for any help!
Bests,
Virag
