the keyboard ... I have it hook up to my Compaq laptop and my Logitech access keyboard right now and it seem to be work reasonable well . none of the dedicated accessory key work such as volume etc. . but as I rarely use these key it be not a great loss . my motivation for purchase this device be that it be a cheap and fast band aid solution , to my dislike of laptop keyboard . grant I have every intention of buy a dedicated full size usb keyboard in the very near future . but for the moment this adaptor suit my purpose . the mouse ... my laptop mouse be Logitech notebook mouse which be usb wireless ... however as I hear so many negative about the mouse adaptor as a experiment I try the mouse adaptor with a older model -lrb- roller ball NOT Laser -rrb- Compaq mouse . and it seem to work fine on that device as well . with no disrespect intend towards buyer and user of Dell Computers or the capability of Dell Computers . I have hear in the past that they can be a little temperamental with `` foreign '' device . so I would advise those user to purchase these sort of adaptor with caution .
