usb touchpad not working properly on CURRENT with usb2

[Boris Kotzev]

Hi,

The touchpad of my laptop is not responding properly to input anymore. It used
to work fine with the old usb stack.

The laptop is running CURRENT from yesterday:

FreeBSD zembla.universe 8.0-CURRENT FreeBSD 8.0-CURRENT #0: Wed Mar  4 17:30:05 EET 2009 
user at zembla.universe:/usr/obj/usr/src/sys/CUSTOM  amd64

When I move my finger horizontally on the touchpad of the laptop, the cursor
moves up and down. Moving the finger vertically moves the cursor a little and
then it stops. Pressing the touchpad button moves the cursor to the right.

The touchpad is detected as:

ugen0.2: <Apple Internal Keyboard / Trackpad Apple Computer> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON

Resetting the touchpad  produces the following dmesg output:

What other information should I provide to help solving this problem?
