No, I can see it on the device manager list, so my computer sees it, but I cannot connect to it. It looks like it trys to connect serially rather than through USB. Is there another setting that needs enabling for the USB to work?

Yes, I already installed the USB driver, so it's communicating.

Good afternoon, I've recently received a machine with a Unitronic JZ20-J-T18 and I'm trying to go online with the PLC using the micro-USB port on the side. I don't even have a copy of the program. Right now, I just plug in, open U90, click upload, but it keeps saying no communication? I'm unsure what to do after this step. I've read somewhere that I should be able to program through the micro-USB port? Any help on this would be appreciated, thanks!
