I’m having problems getting the USRP up and running with GNU Radio.
System: Fedora Core 5
GNURadio 2.8
everything builds and passes make check.
some of the test apps in the usrp-0.12/host/apps directory work such
as:
usrper load_standard_bits
usrper led1 on/off
so i know i’m able to talk to the USRP, but the following apps dont:
test_usrp_standard_rx
test_usrp_standard_tx
both fail with an error message of not being able to claim the USB
interface. i also get this error when attempting to run any of the usrp
examples in the examples tar ball.
any help would be appreciated,
rick
I actually just ran into this same problem myself.
Try running the same commands as root, they should work fine.
To be able to run them WITHOUT becoming root, you need to set up fedora
to
change the ownership of the usb device. This used to be handled by
hotplug, but under fedora core 5 it is done by udev.
This link describe how to set up a gps device in fedora core 5 so that
any
user can access it. Follow the same instructions, but use the following
changes:
http://www.gpsbabel.org/os/Linux_Hotplug.html
idVendor: fffe
idProduct:0002
Then unplug and replug the usrp. That should make it accessible to any
user.

Thanks for posting this.
If you have a rev 4 USRP you may need to change idProduct to 0004

Probably a permission problem on /proc/bus/usb//
Isn’t there a hotplug or udev script out there somewhere that fixes
this for FC5?
