From 41de326eafa6eff71c6ca00ae27c6be235c65a6d Mon Sep 17 00:00:00 2001 From: Christian Ohm Date: Tue, 21 May 2013 01:31:08 +0200 Subject: HID: Add driver for Holtek gaming mouse 04d9:a067 This mouse is sold as Sharkoon Drakonia and Perixx MX-2000 and reports a too high usage maximum and logical maximum. This driver fixes the report descriptor so those values don't exceed HID_MAX_USAGES.

So we introduce a new HID 'quirk' driver with a raw_event handler where we take care of those events. What we need additionally is an input_configured hook, because the device does not mention anything about PRESSURE and TOUCH in its report descriptor, but it actually generate those. So we set the bits in the corresponding input_dev in that hook. Thanks to Petr Ostadal who was willing to test the driver. The rest of Cc's listed below had something to do with that driver over the years in our enterprise tree.
