* The report descriptor of some Holtek based gaming mice specifies an

* excessively large number of consumer usages (2^15), which is more than

* HID_MAX_USAGES. This prevents proper parsing of the report descriptor.
|
|

|

* This driver fixes the report descriptor for:

|
* - USB ID 04d9:a067, sold as Sharkoon Drakonia and Perixx MX-2000

|
* - USB ID 04d9:a04a, sold as Tracer Sniper TRM-503, NOVA Gaming Slider X200

|
* and Zalman ZM-GM1
|

* - USB ID 04d9:a081, sold as SHARKOON DarkGlider Gaming mouse

* - USB ID 04d9:a072, sold as LEETGION Hellion Gaming Mouse
