Both NBT and EVO recognize USB adapter. I've flashed over this adapter in past, the process is the same as flashing over Ethernet_63, just the HU IP is different. You could fire up wireshark and filter for 'arp' frames to see the IP of the HU.
As for timing, make sure your E-Sys is set up with largest timeouts possible in settings. When starting flash process, as soon as the HU screen turns black, you would want to issue a command for rescue_mode for NBT or programming mode for EVO. Timing is critical, so you may need multiple attempts to succeed. There is not much time between the moment the screen turns black and E-Sys stops waiting for bootloader mode.
If you send command too quickly, E-Sys would not be able to switch the HU into black screen mode and fail. If you send the command too late, E-Sys will timeout with an error waiting for a response.
If sending command to NBT through tool32, you want to issue the command twice, since it will fail on first attempt, but go through on second.
