It seems that USBSerial is not implemented yet, can I use it with RawDevice?
In theory yes you can.
Is this for commercial use?
Welcome to the community.
Can we have vote on this?
I’d like to see multiple serial port support for the USB host port as this would allow modems to have a data connection at the same time as being able to check SMS, signal etc. Also, some modems support GPS too so we could have a mobile platform without resorting to using the CMUX protocol and the subsequent development that would need. It would seem that USB serial would be easier to implement than CMUX.
I vote yes to USB serial support.
