3D printing via USB [Serial]

 My printer does it. It did before I rebuilt my Kubuntu system. As it is now Cura does not recognize a USB connected printer. 

With the printer switched on lsusb gives me:

Bus 001 Device 005: ID 1a86:7523 QinHeng Electronics CH340 serial converter

So I am looking for the ch340 driver. I think this is what I had to do last time.

I have found:

I need to relearn how to drive #make to get this installed.
