A particular touchpad (SIPODEV SP1064) refuses to supply the HID descriptors. This patch provides the framework for overriding these descriptors based on DMI data. It also includes the descriptors for said touchpad, which were extracted by listening to the traffic of the windows filter driver, as well as the DMI data for the laptops known to use this device.
