Subject: [PATCH] usb: quirks: add NO_LPM quirk for Logitech Screen Share
Date: Wed, 26 Feb 2020 14:34:38 +0000 [thread overview]
Message-ID: <20200226143438.1445-1-gustavo.padovan@collabora.com> (raw)
From: Dan Lazewatsky <dlaz@chromium.org>
LPM on the device appears to cause xHCI host controllers to claim
that there isn't enough bandwidth to support additional devices.
