    Subject[PATCH 4.14 093/126] usb: quirks: add NO_LPM quirk for Logitech Screen Share
    Date
    From: Dan Lazewatsky <dlaz@chromium.org>

    commit b96ed52d781a2026d0c0daa5787c6f3d45415862 upstream.

    LPM on the device appears to cause xHCI host controllers to claim
    that there isn't enough bandwidth to support additional devices.
