[SOLVED] Howto enable FTDI driver



I d like to know how to enable FTDI driver ( serial USB <=> TTL ) on a mangOH Red With Legato and wp7702 :

root@swi-mdm9x28-wp:~# legato version

What is the process ?



Last time I tried, on a mangOH Green, it just worked.

Have you tried it?



I can’t see any ttyUSBx

What tty can you see on your Green ?



Hi use FTDI on my board:
See this link : WP76 R9 and usb serial ftdi
You have to use this command " modprobe ftdi_sio" to enable FTDI


Thanks you, It works perfectly:

root@swi-mdm9x28-wp:~# modprobe ftdi_sio
root@swi-mdm9x28-wp:~# ls /dev/ttyUSB*
