SWW13/hid-acer

Acer HID Quirks

hid-acer kernel module

Acer keyboards e.g. in Acer SW5-012 use synaptics touchpad USB ID (06cb:2968, 06CB:2991 & 06CB:74D9) and have the following issue:

• The report descriptor specifies an excessively large number of usages and logical max (2^16), which is more than HID_MAX_USAGES. This prevents proper parsing of the report descriptor.
