Apple Optical USB Mouse no more working with current.

Hi,

I upgrade today to 189774 and my Apple optical USB Mouse does not longer 
work.

Here the details:

This is with a GENERIC Kernel with fw disabled.

Do I need to configure anything or is this a potential issue with the 
usb stack?

world is up-to-date, means 2 days old.

TIA,

Andreas
