Can't access by serial (SOLVED)

[Andrew Walker]

I don't seem to be able to connect via USB on either Ubuntu 17.10 or another machine with Gentoo installed. modinfo cp210x gives a whole load of info

depends:
intree: Y
name: cp210x
vermagic: 4.13.12-gentoo SMP mod_unload

on both machines but neither appear after doing lsusb or dmesg. The Gentoo box definitely has the kernel module installed as I built the kernel. Is this a kernel error and is anyone else experiencing this?

Ignore my post, I'm an idiot, I forgot that the Omega power dock doesn't support login with screen despite having the micro USB port!
My bad!
