HP USB-C DOCK G4 shown as unknown device

HP Recommended
Microsoft Windows 10 (64-bit)



The USB-C Dock was having issues with the monitors on the displayports being recognized. So I decided to upgrade the firmware to version F.37 Rev.A

Downloaded it from here:

After the upgrade the monitors are recognized and NIC is working but no USB ports are working. And I have an unknown device in the device manager.

That device has VID 04B4 and PID 6507

I found out that Vendor ID 04B4 is Cypress Semiconductor Corp. The Product ID I am unable to find.


Any idea which driver this requires? Windows does not recognize it and Windows Update can't find a driver for it.
