From: Kyle Williams <kdgwill@xxxxxxxxxxxx> Description: Some USB device / host controller combinations seem to have problems with Link Power management. In particular it is described that the combination of certain Logitech uvc devices and other powered media devices such causes 'not enough bandwidth for new device state' error. This patch enables the USB_QUIRK_NO_LPM quirk entries for all connected Logitech UVC devices indicating LPM should remain disabled for the device.
