In order to use WBX, I install git repo on my ubuntu 9.04.
When I do usrp_benchmark_usb.py, it goes well with 2MB test, but failed at
4MB showing device busy error.
The output is attached below. I tried other daughter boards (RF2400), no
problem. So I guess it is related to the WBX.
Testing 2MB/sec... usb_throughput = 2M
ntotal = 1000000
nright = 999156
runlength = 999156
delta = 844
OK
Testing 4MB/sec... usrp_open_interface:usb_claim_interface: failed interface
1
could not claim interface 1: Device or resource busy
usrp_basic_tx: can't open tx interface
