Problem with GNU radio installation in UBUNTU 8.10


#1

Hi,
I am trying to install GNU radio on Ubuntu 8.10.
I followed the script method (apt-get) step by step as described in
wiki.
All the packages are completey installed without any error.(during
installation). But still GNU radio cant access the USRP. I am using
USRP1 with my sony vaio fw160j.
Following error occured when i tried to run th example
usrp_benchmark_usb.py

gohar@ubuntu:~$ python
‘/usr/local/share/gnuradio/examples/usrp/usrp_benchmark_usb.py’
Testing 2MB/sec… usrp_open_interface:usb_claim_interface: failed
interface 0
could not claim interface 0: Operation not permitted
open_nth_cmd_interface: open_cmd_interface failed
usrp: failed to load firmware /usr/local/share/usrp/rev2/std.ihx.

usrp_tx = usrp.sink_s (0, tx_interp)

946, in sink_s
return _usrp1.sink_s(*args)
RuntimeError: can’t open usrp1

Can any body help me out.
Further i have to test the files of GSM scanner project. Can i do so
using the latest stable release of gnu radio or i have to use some
previous releases? Any suggestion?

Thanks

The at least two possible reasons I can think of that would generate
your symptoms:

  1. You don’t have access to the hardware. The binary package install
    adds the group ‘usrp’ and allows members of that group to access the
    USRP, but you need to add your userid to that group (this is in the
    wiki page you used.)

  2. You have a physical cabling issue (such as not using a USB2.0
    standard rated cable).

A simple test if this is your error is to run the benchmark as root. If
it works, you need to fix permissions to the hardware.
