There is a desire to use the capabilities of USB host to control a single device by serial port.
When connecting in dmesg sees the device correctly IDs him. But in /dev/ there is no hint on the com port (there is a standard UART from Tegra 4 and ttys0-3 that can not be opened under any circumstances).
Maybe someone will be able to tell, in what side to dig?
Oh yeah, the device — Transformer Prime, for reference.
