I regularly use a usb-stick on my home computer (RedHat 9). Up to kernel 2.6.6, it worked correctly, but

This is probably something unique to my home machine - my work computer
uses the same kernel version with RedHat 8 and does not show this problem.
I notice that IRQ 5 seems to be shared by my network card and by USB, and
it is disabled as a result of this problem, so if I were using a LAN, I would
lose access to the LAN after this problem.
This sounds exactly like a problem that a lot of other people have had. You will probably find the answer in
http://bugme.osdl.org/show_bug.cgi?id=2243
Try applying the patch given in Comment #89.

removing ehci_hcd (either by recompiling or by rmmod ehci_hcd) *before* plugging
my USB stick allows the stick to be recognized as in kernel 2.6.6 - this may indicate that
the bug either lies in ehci_hcd, or is triggered by it... or maybe just that USB 2.0 support
in my mainboard is broken :-(
Anyone who has the "nobody cared about IRQ xxx" message AND notices that ehci_hcd
is enabled/loaded, please consider removing the ehci_hcd module (if compiled as module) *before*
plugging any USB device, or else recompiling the kernel without ehci support, and test if the problem
goes away.
Hope this helps
