Go into Windows Settings -> Devices

Connect the 50g and power up.

If you see "HPx9G+ Device" in the list of "Other devices" then the driver is installed successfully.

Note that the driver needed to communicate with the Prime is included with its ConnKit, so if you installed a USB driver separately then it is NOT the one for the Prime.

The ConnKit for the HP 50g (Conn4x) is linked to on this page: http://www.debug4x.com/
