UD3900 Unable to Recognize driver on Windows 7 with HP Folio Machine

My UD3900 show up yesterday from Amazon and followed the instructions and installed the correct driver for Windows 7 (version 7.5) but my HP Folio machine can’t recognize the driver. And even though the driver is installed when I check the device manager I have the device listed there as other with an error sign.

Appreciate any help on this.
