I still have a request for UART over USB HOST so that we can support a Modem. I know PPP over serial works but with UART, the modem exposes more than 1 UART so you can still interrogate for SMS when connected to PPP on another port.

This certainly an interesting one but to do it right USB will also have to support multiple interfaces. Like you said, it is not just a UART over USB. It is multiple UARTs.
