What: /sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/<hid-bus>:<vendor-id>:<product-id>.<num>/quirks
Date: November 2011
Contact: Benjamin Tissoires <benjamin.tissoires@gmail.com>
Description: The integer value of this attribute corresponds to the
quirks actually in place to handle the device's protocol.
When read, this attribute returns the current settings (see
MT_QUIRKS_* in hid-multitouch.c).
When written this attribute change on the fly the quirks, then
the protocol to handle the device.
