[Discuss-gnuradio] USRP/USB, problems connecting

I'm having problems connecting my USRP to my computer (running Open-Suse
with a  2.6.22.13-0.3-default kernel). I know the USRP works, I've tried
it with another machine (using the same gnuradio-version), and the admin
claims he hasn't fiddled with the computer concerned. This is what I get
(as root or as user, using rx or tx):

>>> from gnuradio import usrp
>>> src = usrp.sink_s()
usrp_open_interface:usb_claim_interface: failed interface 1
could not claim interface 1: No such file or directory
usrp_basic_tx: can't open tx interface
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.5/site-packages/gnuradio/usrp.py", line
230, in __init__
    fpga_filename, firmware_filename)
  File "/usr/local/lib/python2.5/site-packages/gnuradio/usrp1.py", line
946, in sink_s
    return _usrp1.sink_s(*args)
RuntimeError: can't open usrp1

The USRP is connected alright, otherwise the error message would look a
bit different. ls -lR /dev/bus/usb returns [excerpt]:

/dev/bus/usb/001:
insgesamt 0
crw-r--r-- 1 root root 189,  0 21. Jan 15:32 001
crw-rw---- 1 root usrp 189, 10 22. Jan 15:08 011

There it is. I uninstalled and remake'd and re-installed GNU radio from
the 3.1 branch (out of SVN), that didn't help. dmesg seems OK, too:

usb 1-1: new full speed USB device using uhci_hcd and address 12
usb 1-1: new device found, idVendor=fffe, idProduct=0002
usb 1-1: new device strings: Mfr=1, Product=2, SerialNumber=0
usb 1-1: Product: USRP Rev 4
usb 1-1: Manufacturer: Free Software Folks
usb 1-1: configuration #1 chosen from 1 choice


Could someone please give me direction where else I can look? I've seen
this problem crop up in the archives, but I couldn't find a solution.

Thanks,
Martin
