Hi, Dear All,

I’ve just installed cygwin and gnu radio in my laptop. I’m trying to run
usrp_benchmark_usb.py. and i get this message:

usb_throughput = 2M
ntotal = 1000000
nright = 998019
nlength = 998019
delta = 1981
OK
Testing 4MB/sec

does anyone know about this. because it looks error ,
“usb_control_msg:sending control message failed” . but it looks OK as
well,
usb_throughput = 2M

nlength = 998019
