Win CE: Connect via USB OTG to Windows or Mac

Technical Support

I want to be able to connect my T20 / VF61 (Win CE) based device to a PC (Windows or macOS) via USB. The PC is USB host and the T20 is the USB device. Because I don’t want to have to supply my own Windows driver, I’d like to set the USB device PID / VID to the values that make it a WinUSB device and thus use the Windows default driver.

  • How can I set the VID and PID of my T20 / VF61 in USB OTG mode?
  • Which Win CE APIs can I use to control, send and receive data?

Thanks and greetings from Franconia!

A quick follow up question:
Is it possible to set up the USB OTG port to come up as a generic HID device for the connected host PC?

We recently wrote a blog post about that topic here.

The article links also to the developer website where we describe the setup on Host and Client side over WinUSB: WinCE Serial Over USB | Toradex Developer Center .

I think this way is the more generic approach other than let the device pretend to be a HID device.

If you want to have a proper setup, you would have to get a USB VID. To start with you may could use one from pid.codes.

Hey, that should work! Once again I’m impressed by the support Toradex provides for me. Thank you Samuel!
