USB CDC driver

I have a usb cdc device that works in windows 7,8,10 using window’s cdc driver. I’m connecting this device to T30 running wince7. AFAIK wince7 has cdc driver but I haven’t been able to make it work. When I insert device, a dialog opens that says ‘Unidentified USB Device’ and prompting for a driver name. I was hoping it to be a pnp.
Where can I get the cdc driver for wince7? Do I have to install it separately, manually, etc? Is there documentation on how to do it?

Do you have some more details about the device you want to attach? Did you already check our collection of information for USB2Serial drivers. You find it on our developer site.
