From b2d8dd6455350d10e35533fe209e7c11170f8deb Mon Sep 17 00:00:00 2001

Subject: [PATCH 7/8] HID: holtek: fix mouse probing
An overlook from the previous commit: we don't even parse or start the
device, meaning that the device is not presented to user space.
Fixes: 93020953d0fa ("HID: check for valid USB device for many HID drivers")
