Try to run the example as root: sudo python test_counting.py
If the program runs fine, then your user account does not have
permission to access the USRP. Follow this guide:
http://gnuradio.org/trac/wiki/UdevConfig to setup permissions.

After installing the gnuradio on Fedora 6, I wanted to run
test_counting.py (or any program in the gnuradio-examples/python/usrp
directory) but I get the following error:
Usrp_open_interface:usb_claim_interface: failed interface 2
Could not claim interface 2: No such file or directory
...
( traceback info )
...
RuntimeError: can't open usrp1
I've added to the PYTHONPATH with
/usr/local/lib/python2.4/site-packages. I plugged in an usb thumbstick
to see if I could use the usb ports and it worked fine. Does anyone
have any guidance?
Thanks!
