I'm connecting multiple devices to SharePort on DIR-628. I'm using a HP USB hub, m/n PUSB150. I cannot successfully access get all devices connected to the HP hub. I have a Maxtor OneTouch 4, HP L7555, a FLASH drive, and a Casio EX Slim docking station. The latter has trouble being recognized and that is not my biggest concern. I'd like to get full-function from the previous two devices. Please advise with your experience. Thanks.
