I'm glad you found a workaround, since this problem got tougher with the
new 2.6.28 kernel.

The possibility to control the mouse interface was moved to the hid
module, which is now built into the kernel. You'd have to hack the
usbhid module with something like this
untested-and-not-compiled-and-unsupported piece of code:

diff --git a/drivers/hid/usbhid/hid-core.c b/drivers/hid/usbhid/hid-core.c

                        dev_err(&intf->dev, "can't add hid device:

I am leaving this snippet as a pointer to a possible solution for anyone
who feels like picking it up. Please understand that I will not
regularly answer emails regarding this or other jaunty issues. I will
hopefully see you gentlemen during the karmic work, as that is the next
release I will involve myself in.

So long,
Henrik
