A few more things to try:
When you run MFDeply can you choose USB -> USBizi and get a ping response?
If not, can you push the reset and see The US Bizi option pops up eventemporarily?
Have you deployed any programs prior to this problem? Sometimes existing code can interfere such as in hibernate mode. In that case bootloader can be used to erase existing deployment.
One other thing although it probably doesn’t apply to your problem is if the serial debug jumper is installed you won’t be able to use USB debug for deployment. Since you have to solder in the jumper or jumper connector for the Domino you probably would have mentioned that.
Good luck. There’s a lot of help available via the forum if you’re still stuck.
