Description of problem:
I have a Toshiba Satellite with a Synaptics Touchpad that includes not only a third mouse button but also a programmable LC Display and the ability to generate Button 4 and 5 Events by moving along the sides of the Display.
There is a driver for this pad available at http://www.uni-jena.de/~p1stja/linux/cpad.html, however this driver cannot be used out of the box with FC3, because the kernel (usbhid) grabs the device before the cpad module can be loaded.
The attached adds a quirks line to the kernel so that HID ignores the device and the cpad driver can be used.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Apply the patch to the current FC3 kernel, rebuild, reboot
Actual Results: With the RH kernel, the cpad device gets grabbed by the usbhid, making its advanced features inaccessible.
Expected Results: With this patch, the cpad driver can expose its funcionality to the user space.
cpad driver is available from http://www.uni-jena.de/~p1stja/linux/cpad.html
