+ Say Y here if you want to be able to query and change the
+ HID "blacklist" at runtime. This enables the
+ /proc/usbhid/device_quirks file, which contains a list of all
+ active USB HID quirks.
+
+ The list consists of four entries per quirk: a 16-bit USB vendor
+ ID, a 16-bit USB product ID, a 16-bit product ID mask, and a 32-bit
+ quirks field. To update the quirks list, write a string to the
+ file, e.g.:
+
+ echo '0xcd4:0x1:0xffff:0x4' > /proc/usbhid/device_quirks
+
+ If a quirk exists for this (vendor ID, product ID, product mask)
+ combination, its quirk value will be replaced with 0x4; otherwise,
+ a new quirk will be added. Quirks may be removed from the list
+ by using 0x0 for the quirks value. Quirks values are defined in
+ include/linux/hid.h. Multiple product IDs can be covered by
+ using other values for the product mask.
+
+ If unsure, say Y.
