Re-enabling USB2TTL serial

[neagix]

Hi there

I am using OpenWrt 19.07.3 on a VoCore2 Ultimate and for some reason there is no more USB2TTL. I connect the VoCore2 to a laptop and it does not show any `/dev/ttyACM0`; this was working fine previously.

I did not change anything radical in OpenWRT, I have actually been using only LuCi to make changes.

It stopped working since when I changed the SSH port, but I can't believe that it is related.

Any idea what to check? `/etc/inittab` looks fine and matches what is in the `/rom`

Thanks

VoCore2 Ultimate USB2TTL is not on VoCore2 main board.
It is a chip on the dock. So it is not related to any firmware on VoCore2.
Just check if your USB cable data lines broken. If one USB D+/D- broken you will also can not find the USB device on your PC but you still able to power on VoCore.
