Oh, but they would. There's been a slew of USB issues caused by a
single patch in the 2.6.32.x stable tree that, iirc, only just got
fixed in one of the last two or three stable releases. Not sure
exactly what stable series kernel version the currently available
Ubuntu 10.10 kernels are based on. Its a possibility its that at play
here, anyway.

As an aside, it would be nice if other distros would version their
kernels in a meaningful way that actually let you know from nothing
more than uname -r what upstream kernel it was really based on... We
started doing that a few years ago now in Fedora. (I wrote most of the
rpm spec file infra to make it happen, extremely happy w/how its
worked out).
