I finally got the usrp up and running. I am having two problems.
1. I believe that the data rate is overflowing the usb line becuase
the sound from usrp_wfm_rcv.py is jerky and the text UaUaUaUaUa... is
streaming to the screen (about 1-2 times per second). I am running
the pre-compiled packages available through Ubuntu on a Dell inspiron
1501 1.6 GHz processor. Would compiling from scratch help? Is there
a way to decimate the data before it comes across the usb?
Use the following option to usrp_wfm_rcv.py:
-O plughw:0,0
And see if that helps. If it does, the problem was that your sound card
doesn't directly support 32 ks/s, so turning on the ALSA resampler fixed it.
2. I need to unplug and plug the usrp after each use otherwise I get
the error
"RuntimeError: Unable to find USRP #0". Cycling the power is the only
work around I have at this point. Any suggestions on how to fix this
one? Full disclosure: I had to copy the files from
/usr/local/share/usrp/Rev* to /usr/share/usrp to get the firmware to
automatically load do I need to do anything else?
I think this is a recent Ubuntu problem. Which version do you use?
