The at least two possible reasons I can think of that would generate
your symptoms:

1) You don't have access to the hardware.  The binary package install
adds the group 'usrp' and allows members of that group to access the
USRP, but you need to add your userid to that group (this is in the
wiki page you used.)

2) You have a physical cabling issue (such as not using a USB2.0
standard rated cable).
