I want to add a virtual com port to the AN75779 Example.
So, I increased the number of interfaces, the total length of the descriptor.
I also changed the bNuminterfaces for each uart descriptor.
But It doesnt work. I think, there is something with the usb descriptor.
If you have any suggestions you are more than welcome.
In the descriptor file, under the "Configuration Descriptor," new descriptor information has to be included to add the UVC interface. The length of the "Configuration Descriptor" and the "Number of interfaces" sections has to be updated accordingly.
Also, the endpoints must be configured in the device firmware and the functionalities for the new interface must be included in the firmware.
