Touchpad stops working when coming out of suspend on MacBookPro5,2

[Rainer Rohde]

This is a regression - just started a couple of days ago.

When coming out of suspend, my MacBookPro 5,2's touchpad stops working. The mouse cursor is still visible, and I can right-click and get a context menu, but I am unable to move the mouse cursor around my screen.

On the other hand, my external USB mouse works just fine.

Status changed to 'Confirmed' because the bug affects multiple users.

[Eirik Wang (eirilwan)]

Also bug on Lenovo ThinkPad W520. Only touchpad stops working. The trackball works fine.

[Eirik Wang (eirilwan)]

To get touchpad to work after suspend, reload module "usbhid"
sudo rmmod usbhid
sudo modprobe usbhid

[Calum MacRae (phyrne)]

As eirilwan said, reloading the usbhid module will get it working.

You can put this into a script to be called by pm-utils. I've provided the instructions on how to do so in this Ubuntu Forums thread:

I can confirm the same issue with a MacBook air 13" 4,2 running Ubuntu 12.04
