That would be a good idea. Maybe even a kernel-option to switch the
behavior for people who don't use a module but compile it in ("Enable
workaround for broken devices").

The main problem is the binary ethernet-driver from nvidia for the
nForce2. And that's not a kernel-problem... But I already have a
realtek for my PCI, so this problem will go away.
And during testing -test3 on my notebook, it ate my ext3-fs, so this
thing is not going onto my desktop system (although I've got backups)
Report is on the way.

It works, just copied 2.4.21/drivers/usb/host/* to
2.4.22/drivers/usb/host/ and recompiled the kernel.
All 2.4.22 errors disappeared, so my problem is definitly related to the
new host-code in 2.4.22.
Would be great if we could figure the problem out before 2.4.22 goes
stable.
