From b8e98f1c47b743e56f8ebe21006199cefd577ce5 Mon Sep 17 00:00:00 2001 From: Jiri Kosina Date: Mon, 18 Jun 2007 17:41:14 +0200 Subject: [PATCH] HID: Add NOGET quirk for all NCR devices Devices manufactured by NCR have userspace hiddev-based drivers, which do all the necessary device querying by themselves. The devices must not be queried directly by the generic HID driver, as reported by NCR engineers.
