From 2d64f31bdfbb2ea66cbd4271c079f11808c79c28 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 8 Jul 2015 14:03:41 +0200 Subject: usb-storage: Add ignore-device quirk for gm12u320 based usb mini projectors Grain-media GM12U320 based devices are mini video projectors using USB for both power and video data transport. Their usb-storage interface is a virtual windows driver CD. The gm12u320 kms driver needs these interfaces to talk to the device and export it as framebuffer & kms dri device nodes, so make sure that the usb-storage driver does not bind to it.
