[Discuss-gnuradio] usb_control_msg error

[Ahmet Hasim Gokceoglu]

Hi,

I have been trying to test my USRP with usrp_benchmark_usb.py for a couple of days but there is a problem that I still couldn't solve. Each time I run the program I get;

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
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

I have high speed usb connection and one other thing to note is that after I run the program the green LED that blinks with 2Hz stops blinking and remains ON. The TVRX and RFX2400 daughterboards are also mounted. I don't know whether any kind of setting for the daughterboards or motherboards are missing or wrong to give such kind of usb_control_msg error. Does anybody have any idea?
