I had to download a separate inf-file for the USB-Serial converter. I noticed the drivers folder contains multiple similar inf-files that can be combined to a single file if it ends like:
;------------------------------------------------------------------------------
; Vendor and Product ID Definitions
;------------------------------------------------------------------------------
; When developing your USB device, the VID and PID used in the PC side
; application program and the firmware on the microcontroller must match.
; Modify the below line to use your VID and PID. Use the format as shown below.
; Note: One INF file can be used for multiple devices with different VID and PIDs.
; For each supported device, append ",USB\VID_xxxx&PID_yyyy" to the end of the line.
