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 A. KhanDoctral CandidateUniversity of New South

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.--PaulPhaysal Khan wrote: 


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?!...   Faisal A. KhanDoctral
