Im not familiar with USB Tethering.
I have custom device which is connected to another by serial wire.
I would like if there any chances to improve stability, and performance of this connection, by replaicing it by USB tethering.
This is my solution:
|1 DEVICE|<=>FTDI<=>SERIAL<=>FTDI<=>|2 DEVICE|
To my device this serial is connected thru FTDI.
I have USB port (/dev/ttyUSB_N for example) in my system which is responsible for this type of connection.
Im using PPPD and L2TP to make it possible to bridge this connection with normal ETH.
I have usb0 interface in my system.
Is it possible to tell usb0 to use /dev/ttyUSB_N ?
usb0 is able to use bridge without PPPD and L2TP.
