Subject: Rumble support for Jess/Saitek "color rumble pad"

Hello developers (and testers)

The attached pad adds supports for another gamepad to the hid-pl driver.
The "color rumble pad P580" marketed using the "Saitek" brand in
Germany, and using a USB Vendor ID attributed to "Jess" seems to be
electronically identical to the 4-field variant of the "Green Asia"
gamepad.

The pad has been tested to support rumble strengths up to 255, not just
127. Currently the patch discriminates the pads by an if on the vendor
ID, a bit in the driver_data field with definitely do better, but I
recommend the owners of the 4-field green asia pad to verify whether the
maximum rumble strength is indeed only 127, otherwise the condition
should be removed entirely and 255 used in all cases.

Regards,
  Michael Karcher
