Genius Gila Gaming Mouse presents an obviously wrong report descriptor. the Consumer control (report ID 3) is the following: 0x05, 0x0c, // Usage Page (Consumer Devices) 105 0x09, 0x01, // Usage (Consumer Control) 107 0xa1, 0x01, // Collection (Application) 109 0x85, 0x03, // Report ID (3) 111 0x19, 0x00, // Usage Minimum (0) 113 0x2a, 0xff, 0x7f, // Usage Maximum (32767) 115 0x15, 0x00, // Logical Minimum (0) 118 0x26, 0xff, 0x7f, // Logical Maximum (32767) 120 0x75, 0x10, // Report Size (16) 123 0x95, 0x03, // Report Count (3) 125 0x81, 0x00, // Input (Data,Arr,Abs) 127 0x75, 0x08, // Report Size (8) 129 0x95, 0x01, // Report Count (1) 131 0x81, 0x01, // Input (Cnst,Arr,Abs) 133 0xc0, // End Collection 135 So the first input whithin this report has a count of 3 but a usage range of 32768. So this value is obviously wrong as it should not be greater than the report count.

Still, my patch queue is growing, and I would like you to consider this patch for 3.11. FYI, my patch queue is the following: - one hid-multitouch patch which set the quirk NO_INIT_REPORTS for mt devices - few hidp cleanup related to the wrong init_report called during start - re-implement the hidinput_input_event callback in hidp to allow LEDs to work with BT keyboards - some trivial devm conversions for some special HID drivers - add devm_hid_allocate_device which allow to devm-ize i2c-hid All of these are cleanups/enhancements, so I think we can postpone those patches to 3.12 to get a maximum testing time.
