[Discuss-gnuradio] Unable to find USRP #0 in kernel 2.6.24-rc4-gd7f0b481 on Fedora 7

[gef]

I installed kernel of 2.6.24-rc4-gd7f0b481 for Fedora 7 in PS3 following
http://www.gnuradio.org/trac/wiki/PS3FC7Install.
The linux system runs well.  Then I installed GNU radio as told in above URL.
Everything went well too. However, I could not get USRP work. I am not sure
whether it is because of the new kernel or something else. Therefore, I listed
the test script and output below for running usrp_benchmark_usb.py and also the
output from dmesg to test USB connection.

Your help will be very appreciated!
