| Subject | [PATCH 3.16 175/305] usb: quirks: Add no-lpm quirk for Acer C120 LED Projector |
| Message-ID | <s62f8-7AQ-47@gated-at.bofh.it> |
3.16.37-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Hans de Goede <hdegoede@redhat.com>
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.
