Wanhao Duplicator I3 Plus USB issues

Hi folks,

I've just received and set up my first printer, physical printing is all going fine and printing from SD works, however I'd like to be able to connect via USB. The physical connection for this is fine, the printer is showing up in device manager (windows 10) as a Com port as expected, however none of the software or drivers I've tried are allowing it to connect, I've tried Cura, Matter control and Repetier host, but they all have the same issue. They can tell there's something there, but when they actually try to connect it just times out and hangs on the 'attempting to connect' stage. I've tried the drivers that auto install with Matter control and also the latest FTDI drivers, neither of which solve the issue. I've also tried it on 2 PCs, with multiple USB cables and in multiple USB slots, same issue in all cases. I'm a bit stumped at this point, can anyone help?
