I know it's possible to use USB tty devices on stock Android when an application requests permission to do so. Is it possible to add this support in Sideband? I have some really bad ideas I'd like to play with on stock Android but am currently stuck on this.

Is it now working? Honestly, it's been a while since I used it myself, but it should work out of the box. More or less the same code that RNode over serial/USB uses, and that's fine at least.

As far I can tell it currently does not. It certainly never pops up a dialog requesting access to USB serial devices, even after selecting the option to use a serial interface in "Connectivity" and configuring the settings under hardware an interface never appears in the rnstatus output. I am quite sure the device is there and recognized by the kernel though; a generic serial port application can interact with it just fine. I suppose I need to use the advanced config option and play with that to see what happens as well. Thanks for all the incredible work!

Can you tell me what USB serial device it is exactly? Also the USB vendor ID and product ID (on Linux, you can get them with `lsusb`).
