Re: [Discuss-gnuradio] Cannot Access new USRP2 from Ubuntu 9.10

[Tom Gross]

I usually run find_usrps as root:

sudo find_usrps

also, what is the device name of your gig-e card?  If it's not eth0
you have to specify the device (I think), for example:

sudo find_usrps -e eth1

I wouldn't be surprised if your laptop's default ethernet port is not
gig-e, and is eth0.
