I haven't been using my usrp for a little while. I've been porting my code to
a TI C64x+. I came back to my usrp today and tried to run just a basic receive
for test data for my TI DSP. I got the following error. In usbview I see a
"USRP Rev4" under my ehci controller. I thought it might be the board, so I
grabbed my other usrp, and the exact same thing happened. (This is with
gnuradio-3.1.1 ) So I tried my older gnuradio install, and tried to run
usrp_fft.py... and the same things happened. I checked /usr/local/share/usrp.
It has all of the rbf (see below). Has anyone encountered this before? It was
just a few months back everything was great... I didn't touch gr for a while...
came back and BOOM. :( No joy.
