Logitech Rallybar devices, despite behaving as UVC camera, they have a different power management system than the rest of the other Logitech cameras.
USB_QUIRK_RESET_RESUME causes undesired USB disconnects, that make the device unusable.
These are the only two devices that have this behavior, and we do not have the list of devices that require USB_QUIRK_RESET_RESUME, so lets create a new lit for them that un-apply the USB_QUIRK_RESET_RESUME quirk.
