I have debug printout patches in both evdi and libevdi. In my tests with these versions, the call never happens.

No, I've only ever used this package. I haven't had my displays long enough to use any prior version.

Unsurprising, given my relative lack of luck compared to other people I've had try. :P

I'm willing to try it, but I'm not sure how to go about this. I'm certainly not going to install Ubuntu over top my existing Fedora system. Would booting from a USB image be alright?

I'll try with a powered hub, but I'm not sure what that will do me. Even if it did work, needing a second power socket would kinda suck; I was not anticipating needing a powered hub for this, especially considering I can plug in directly in Windows.

EDIT: Powered hub did not make a difference.

Can you connect one of them and keep it connected for longer to be sure that the firmware image is fully flashed to it? The logo should appear for a moment, then the screen turns black during the update, then the logo should reappear for a moment and soon after this the driver should start displaying pixels. If this succeeds, try with the second screen.

I ensured that the flashing had completed (the monitor did exactly as described). No change.

Eh, slightly unhappy that things have been going slow, but all will be forgiven if we can get things to work.

Thanks for your assistance.
