[Discuss-gnuradio] To free up device or resource that is busy

[Joreen Tan]

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
