Re: [Discuss-gnuradio] using USRP as non-root user

[Ilia Mirkin]

As per a previous posting to this list, you have to set the usbfs
filesystem permissions properly. For example, it looks like

none on /proc/bus/usb type usbfs (rw,devmode=0664,devgid=85)

for me. It may be different for you, but this should be enough to
provide the idea. If not, look at the archives for the previous posting.
Google is your friend.
