I have this problem with Ubuntu, I think thru my upgrades from 10.04
to 10.10 and now 11.04. It is about the device being connected by the
USB code to USB 1.1 even though it is a 2.0 device. It can happen on
boot up or re-connect. I don't have this problem under FreeBSD but do
not have GnuRadio running UHD yet on FreeBSD. I use the UHD code when
running Ubuntu. No VM. The machine is a Dell but the price was right....
