How to connect a micro controller to a CDC device?
You can find some niche products that may fill this by hoogline &quot;USB Host CDC&quot;. As these are niche products your mileage may vary.
The other method is to use a USB OTG or Host compatible microcontroller and roll you own. Many of these microcontroller may have code available so you don't have to code a CDC compatible host driver. At the same time, you could throw a cheap SBC computer like an Raspberry pi or similar to do this instead. A RPi zero may cost the same as a microcontroller that supports usb host and programming time.
