[wellylug] USB Mouse weirdness under Debian/sarge

[John Fouhy]

Hi all,

I bought a new HDD, so I had to reinstall Debian, and I decided to go 
with sarge and the new Debian installer.

My computer, which is a laptop, has a USB wheelmouse.  The mouse works, 
with one problem: when I scroll the wheel, it sends two events, not one.

ie, one atomic movement of the wheel produces this with xev:

-----------------------------

ButtonPress event, serial 28, synthetic NO, window 0x1c00001,
     root 0x48, subw 0x0, time 2429664, (109,91), root:(678,177),
     state 0x0, button 5, same_screen YES

ButtonRelease event, serial 28, synthetic NO, window 0x1c00001,
     root 0x48, subw 0x0, time 2429664, (109,91), root:(678,177),
     state 0x1000, button 5, same_screen YES

ButtonPress event, serial 28, synthetic NO, window 0x1c00001,
     root 0x48, subw 0x0, time 2429664, (109,91), root:(678,177),
     state 0x0, button 5, same_screen YES

ButtonRelease event, serial 28, synthetic NO, window 0x1c00001,
     root 0x48, subw 0x0, time 2429664, (109,91), root:(678,177),
     state 0x1000, button 5, same_screen YES

------------------------------

Left/right/middle click produce just one pair of press/release events as 
per expectation.

Any clues?  I really have no idea where to start looking for the problem 
here.  Everything worked correctly under my previous Debian install 
(when I was still running the latest kernel).
