Hi,
I have recently downloaded the gnu radio software (release 3.1.1) and got
the USRP. I made the dial_tone example work but I have some problems with
the usage of USRP. I tried to do the example usrp_benchmark_usb.py but I got
the error:
Testing 2MB/sec... usb_control_msg failed: error sending control message:
Connection timed out
usb_control_msg failed: error sending control message: Connection timed out
usb_control_msg failed: error sending control message: Connection timed out

RuntimeError: can't open usrp1
since gnu radio is under the directory opt I have set the
USRP_PATH=/opt/gnuradio to be ensure that USRP is searching for the
necessary things in the correct place.
Also the TVRX and RFX2400 daughterboards are also mounted on the
motherboard. So does anybody know why I get such errors? Is something wrong
with the setting of USRP_PATH or is it something to do with the
daughterboards? Should I set also somethings for the daughterboards? I would
appreciate any kind of help since I am stucked with this problem.
Thnx
Ahmet
