USR Device Friend


I am new to Gnu Radio. I am doing a small project on USRP1.

I installed GNU radio on Ubuntu 11.04 using Script provided at GNU Installation went quite well. Now when I connect my usrp1 to
USB port and try to access it using any command it results shows device
not found.

Although I can see my usb device connected on gui interface.

Please help me to resolve this issue or suggest me something.

I hope you will help me out
