From: Hans de Goede <redacted> Date: Thu, 19 May 2016 17:12:20 +0200 Subject: usb: quirks: Add no-lpm quirk for Acer C120 LED Projector From: Hans de Goede <redacted> commit 32cb0b37098f4beeff5ad9e325f11b42a6ede56c upstream. The Acer C120 LED Projector is a USB-3 connected pico projector which takes both its power and video data from USB-3. In combination with some hubs this device does not play well with lpm, so disable lpm for it.
