With kernel 2.6.8, I can't get it to work with either of my external USB
2.0 drives (two different vendors), after some digging I was able to
find some discussion of the problem, which was basically one or more
people involved in the USB core code claiming that vendors are violating
USB specs and that their code expects compliance. Don't know if this is
actually the case (and don't currently have time to check), but, ALOT of
people are apparently having problems with this, late 2.4 and early 2.6
kernels did work with USB 2.0 (i.e. both of my drives), and regardless of
whether or not their assessment is correct, their handling of this needs
to be changed. Overall, I have never been overly impressed with the USB
drive handling, they keep forgetting to put timeouts and error recovery in
their code, it should NEVER be necessary to reboot the system to clear an
error, particularly in a module loaded at run time (worst case you should
simply be able to unload and reload the module), but unfortunately, USB
handling has problems in this area and a reboot is the only cure (even in
2.4 kernels though it doesn't happen to me very often). If I had any
time I'd fix it myself as this kind of problem shouldn't be that
complicated, it's mostly just the time it takes to learn someone else's
code that's the killer. Anyway, I'm back using 2.4 kernels, 2.6 still
isn't ready for prime time, power management is also at least
partially broken, and I've seen other problems. Frankly, 2.6.4 seemed to
work better than 2.6.8, but user-mode-linux (UML) didn't work with the
older 2.6 kernels and I use UML heavily.
FWIW.
