Interestingly, I recently create a VMware VM with Ubuntu Fiesty
specifically for GNU Radio (and an otherwise identical one with
Edgy). I’m using the latest SVN, and it seems to still have this
issue, or maybe something related to it. I even added a comment to
the Ubuntu install guide on the GNU Radio Wiki to that effect, the
primary reason being that this does not seem necessary with the Edgy
VM, and thus it’s a high probability of this being an issue between
the newer Linux kernel and the USRP’s USB code.
Actually, rebooting doesn’t always work either, but more often than
not it does the trick; seems to have something to do with hot-
plugging the USRP versus booting up with it already plugged in, at
least in my testing.
Again, this is with the latest SVN, which includes USB fixes … I
can add that the official 3.0.3 release (before the fixes) just
doesn’t work on Fiesty, so the fixes are getting closer to providing
full (“correct”) functionality under the new kernel. - MLD
