Hi Phil,

in this case, it might be much easier for you to look at the HID debug 
data, rather than the raw USB data given by usbmon.

I would suggest the following:

- grab any recent kernel (anything >= 2.6.23-rc1 is advised)
- compile the kernel with CONFIG_HID_DEBUG and modprobe the hid module 
  with 'debug=1' parameter

Then you'd get HID debugging data from the kernel. If you'd send them to 
me, I can have a look whether the release event arrived from the mouse or 
not.

Thanks,
