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! Andrew GeDid you setup udev as the wiki page instructed? Are you in group usrp? Eric
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/usbThat'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.pyI also tried non-root user within the group usrp. Both results are same as I showed in the previous email.
Thanks, Andrew
