If anyone has any objections, please let me know. ------------------ From: Hans de Goede 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.
