Unable to find USRP

Hi,

Having a few problems getting GNURadio working on my home PC with the
USRP. Can someone provide some tips to help me get it working again? The
problem usrper has problems finding the USRP; it reports “usrper: failed
to find usrp[0]”. All of the examples fail with the “Unable to find
USRP #0” error but I think its more basic than this.

Here’s what the syslog says about the device:

/Oct 23 23:42:54 salyut kernel: usb 5-1: USB disconnect, address 8
Oct 23 23:42:54 salyut kernel: usb 5-1: new high speed USB device using
ehci_hcd and address 9
Oct 23 23:42:54 salyut kernel: usb 5-1: configuration #1 chosen from 1
choice

But it is not there in lsusb:

/Bus 005 Device 001: ID 0000:0000
Bus 004 Device 002: ID 051d:0002 American Power Conversion Back-UPS Pro
500/1000/1500
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 002: ID 046d:0a01 Logitech, Inc.
Bus 003 Device 001: ID 0000:0000

Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000 /

I’m running Debian Etch (AMD 64, 2.6.22 kernel) with the binary GNURadio
3.0.2-2 packages. The 32 bit distribution works fine - I’ve been using
it fine on my lab PC (same Debian Etch setup but 32 bit) for months. I
only moved it there because this problem cropped up and it was as easy
to run it in the lab. Now I want it back at home and I’m foxed by the
problem.

(IIRC this is something to do with USB send/resume and I was hoping it’d
been fixed in the Debian binary by now. Why it works on my lab PC but
not the home PC is also something I don’t quite understand).

If you want the 3.0.4 in Debian (with the mentioned fixes), you can
install build-essential, and get the build-dependencies and build it
yourself.

See http://www.gnuradio.org/trac/wiki/DebianInstall

Or you wait a little bit for the 3.1 release.

Have you checked the permission of the USB device? Have you tried it as
root?
