RE: [Discuss-gnuradio] Big bugs out of nowhere...

Yes.  I double checked just to make sure.  I have a usrp group.  I'm in it.  My 10-usrp.rules file is verbatim from the site.  In the past, I had no trouble accessing the usrp as non-root... but I triple-checked, and the group is setup correctly.

I restarted, and I still get the same behavior.
