I'd start by running usrp_benchmark_usb.py It's a USB speed test
script, and it will verify proper communication with the USRP. The
script is located in /usr/local/share/gnuradio/examples/usrp/ on my
Linux installation.
Do you have a DBSRX daughter card to receive GPS frequencies? If that's
physically installed and the test script mentioned above runs, we can
move on.

Hi Paul,
Finally I got a working system of USRP radio. The FM radio
example runs smoothly (atleast opens up and captures nothing:giving
errors like "usb_control_msg failed: usb_control_msg failed: sending
control message failed, win error, A device attached to the system is
not functioning <--- Is this ok? I am using cygwin, gnu-3.1.1 and
python 2.5)!?
Now, I would like to record IF samples and use Kai Borre Matlab
based GPS receiver to solve for position. Should we proceed with
sample recording. Can you guide me for this?

Faisal,
I'm at Purdue University working toward using the USRP for
GNSS applications. Check my understanding: are you wanting to
use the USRP to record, say, L1 band samples directly to a
data file? Would you be performing all of the signal
acquisition and tracking in post-processing with a separate
software tool?
I'm working on Linux (Debian), but we aught to be able to
trade notes. If you've got a working installation of GNU
Radio, I can show you how to record samples.

Hi,
I am a newbie to USRP, and still struggling to get it
working on my windows machine. I am trying to use cygwin.
I reckon that many ppl have already acquired and tracked
GPS on USRP. Waht I want to do is to capture GPS IF
samples (e.g. at IF=5 MHz) and use a software receiver to
process those IF samples on PC. Any suggestions to start?!...
