Mine shows connected to the printer, and I can control bed preheat through Cura (I don't try printing to it because of the potential for problems though), but my problem is that every time I try to upgrade firmware, the printer reboots and Cura says the upgrade failed due to communications error. Does UM test for that functionality?

I wouldn't recommend using USB printing. It will only add more points of failure, without giving you extra features.
We officially don't support USB printing for the UM2, so it's not something that gets a lot of attention when testing.
