Eric,

I strictly followed the setup udev as the wiki page: 
http://www.gnuradio.org/trac/wiki/UdevConfig.  However, because the new 
kernel 2.6.24-rc4-gd7f0b481uses different sysfs from previous kernel, (I 
browsed through google to get this information), I can't  examine 
/dev/bus/usb after plugging in a USRP simply by the command

$ ls -lR /dev/bus/usb

That's why I listed dmesg result to give more information about USRP 
connection.

On the other hand, I assume the above instruction is used for allowing 
non-root users to access the USRP. I tried root to run

./usrp_benchmark_usb.py

 I also tried non-root user within the group usrp. Both results are 
same as I showed in the previous email.


Thanks,
Andrew
