A very small percentage of computer manufacturers incorporate an ASMedia 1042 or 1043 USB 3.0 Host Bus Controller. Revision 1 thru 4 of this ASMedia chipset does not adhere to the USB 3.0 standard and is not compatible with our kit. If your computer was manufactured with one of these chipsets, you will only be able to use our kit on a USB 2.0 port. For troubleshooting purposes, you can view the manufacturer of your USB 3.0 chipset by viewing the properties of your USB 3.0 controller in the computer's Device Manager. Unfortunately the revision of the chipset is not displayed.
