Single-clicking on things with 2.6.24 very frequently gives a 
"double-click". This does not happen with 2.6.23.8. I wonder what 
broke it? I've grabbed mousedev.c from 2.6.23 and inserted that in 
place of the updated 2.6.24 source, but no change.  So it's not that 
file.

Mmm.. reverting the entire drivers/hid directory to that from 2.6.23
seems to have fixed the problem, so we now know it's in there somewhere.
Jiri: do you have any suggestions that might be more specific than that ?

Could you please run evtest on the mouse device and send me what is 
reported when these false double-clicks happen? Also providing debug 
output of usbhid might or might not be helpful (*)

There were not that many changes in USB HID apart from adding per-device 
quirks for specific broken devices. Could you please try reverting 
c01d50d18, 933e3187, 82eb1219 to see if any of them makes this go away? 

(*) this means compiling with CONFIG_HID_DEBUG and modprobing hid module 
with 'debug=1'.

Thanks,
