Hi,

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

```auto
root@swi-mdm9x28-wp:~# legato version
18.09.0-1-g8350546a_05025499e71b1dbb905fd75d6f797c3a_modified

```

What is the process ?

Regards

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

Have you tried it?

Hi use FTDI on my board:  
See this link : [WP76 R9 and usb serial ftdi](https://mangoh.discourse.group/t/wp76-r9-and-usb-serial-ftdi/1550?u=francois.ravache.neo)  
You have to use this command " modprobe ftdi\_sio" to enable FTDI

Thanks you, It works perfectly:

root@swi-mdm9x28-wp:~# ls /dev/ttyUSB* 
/dev/ttyUSB0

```
