| Subject: usb: quirks: add NO_LPM quirk for Logitech Screen Share |
| |
| 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. |
