USB smart card readers are most full speed devices, and there is no "rate-matching hubs" beneath the root hub on older (e.g. GM45) plat- forms, which has companion OHCI or UHCI controllers and needs cor- responding drivers to communicate with card readers directly plugged into the motherboard, otherwise a discrete USB hub should be inserted between the motherboard and the reader. This time I make inserting linux modules for OHCI and UHCI controllable with option CONFIG_LINUX_USB_COMPANION_CONTROLLER. A linux config for x200 is added as an example. Tested on my x200s and elitebook revolve 810g1.
