By default, USB Synaptics devices are bound to the kernel's generic
USB HID driver.

To use the USB Synaptics driver from this package, run

  /usr/sbin/synaptics-usb-rebind to_synaptics-usb

You can revert back to using the generic USB HID driver with

  /usr/sbin/synaptics-usb-rebind to_usbhid

NOTE:

synaptics-usb upstream is working on getting the driver into the
upstream kernel, so this package is to be considered a temporary
band-aid until Linux 2.6.30 or .31 arrive with synaptics-usb
included.
