Description Henning Schmiedehausen 2005-02-11 12:01:11 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041111 Firefox/1.0

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):

How reproducible:

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.

Additional info:

cpad driver is available from  http://www.uni-jena.de/~p1stja/linux/cpad.html

This bug has been automatically closed as part of a mass update.
It had been in NEEDINFO state since July 2005.
If this bug still exists in current errata kernels, please reopen this bug.

There are a large number of inactive bugs in the database, and this is the only
way to purge them.

Thank you.
