I occasionally see my USB mouse freeze up under X11 on a Red Hat 9
system running 2.5.69-mm3. It completely stops responding to events
until I either switch virtual terminals or restart X, then magically
comes back to life.
There are no entries in /var/log/messages to indicate what might be
going on, so I'm quite mystified.
This is on a system with USB compiled in modular form, though I notice
that, weirdly enough, the refcounts on everything USB-related except
usbcore are zero (i.e. hid, uhci_hcd, ehci_hcd), even though I'm using
the USB mouse right now.

Does this also happem on a non-mm kernel?

The hid driver never increments its user count, even when being used.
Same goes for the USB host controller drivers, so this is not a problem.
thanks,

I'll see. It's not easy to reproduce, though it has happened to me
twice today.

OK, thanks.
