there are 2 kinds of drivers
- Vygisoft VSD2XX New Drivers
- VPower_box_drivers_for_Win_XP
the first ones do NOT define ftdi port, so no virtual comport is assigned, see below
The second ones allow to create a virtual comport, see below
By the way, there is a thierd kind of drivers based on prolific chip pl-2303
