Activating USB OTG by entering "$modprobe g_serial" adds the device /dev/ttyGS0 on ConnectCore 6 SBC (running the firmware "2.0-r3 ccimx6sbc"). Linux/Windows PCs can connect to that USB Serial gadget BUT the baudrate is 9600 bits/s only.
"$stty -F /dev/ttyGS0 9600" works, but it cannot be changed to another baudrate.
Any ideas? Thanks,
