Hi!
 
My optical MS Intellimouse Explorer usb mouse has started to freeze
in X while I leave it idle (ie. i don't touch the mouse) for a while 
(takes from 5s to 1 minute). 

I have found this problem from kernels 2.6.11 - 2.6.12.1. I tested 
also several patchsets, no luck there. There's quite a few usb changes 
in 2.6.11 so this might be related to those. I suspect this might 
be a hardware problem for which the 2.6.10 kernel wasn't too picky 
about. Altough the mouse works flawlessly with W2k.

This is not a X problem. I confirmed this by doing "cat /dev/input/mice".
The output stops after a little idle time. From /proc/interrupts I 
observed that the interrupts from the mice (or uhci_hcd) don't register
at all after the freeze. (Interrupt gets masked?).  

From /sys/bus/usb/devices/ I found that the mouse is still registered
as usb device, altough not triggering any interrupts. All the lights
of the mouse are always on so it does not get shutdown.
 
Changing from console to X (or vice versa) seems to wakeup the mouse. 
Same happens if I reload the uhci_hcd module or start gpm. Mouse does
not freeze unless I keep it idle for a while. I can succesfully use the
mouse if I constantly keep it in motion (not very practical is it ;) )
  
In kernel 2.6.10 I noticed that instead of freezing my mouse it just 
prints debug message from the hid-core: "input irq status -84 received".
 
I have tried to turn ACPI and APIC off (and on), updated my Abit KT7A 
(VIA686 based motherboard) bios to the latest version. No change. 

Any help would be greatly appriciated!
