To free up device or resource that is busy


#1

Hi,

Are there any commands to free up the usb of the usrp from linux?

I’m working on receiving and transmitting signals between 2 usrps but i
realised that, once i start the receiver, even though i exited from the
program in the terminal and reopen the same file, i will get the error
message:

usrp_open_interface:usb_claim_interface: failed interface 2
could not claim interface 2: Device or resource busy

Any help is appreciated! Thanks!Regards,Joreen
