Can't seem to install the HP Officejet 100 mobile printer driver (411a) on an HP EliteDesk 800 G2 DM 35W. Error message reads: "This computer does not have the necessary USB hardware support enabled to allow completion of a USB installation. The installlation cannot continue until this is resolved. Required Action: Click Cancel to exit this software installation. In order to install this as a USB device, please refer to your computer documentation or USB add-in card documentation for more information. If you are sure your computer has the physical USB connectors, refer to your computer documentation about how to enable USB in the BIOS." Any suggestions?
