Enabling virtual com port support in Platform Builder?

I have USB RFID reader and Win CE 6.0 OS. My device is TQ2440 (ARM). The system is in CN language, the reader is available on '$device\COM10' port (After installing FTDI VCP drivers). Everything is fine.

As CN language is not acceptable, I want to build own OS on Platform Builder. I have BSP provided by the device and OS supplier. After building system and installing drivers, I don't see any USB device (COM) which I can use (like '$device\COM10'?).

My question is, which option should I turn in Platf开发者_开发百科orm Builder on, so I could use the reader. As far as I know it's called virtual com port support? But i can't find such an option in PB.

USB Host and Function is checked, so it should be installed...

You will need the windows ce drivers from ftdi. They can be downloaded here:

You can then add them to the platform os build.
