Hard to say, but if the 5V natively to the machine is shot, I’d expect the unit to not work as its systems would depend on it. I assume you measured 5V in reference to the machines GND. Double check your meter against a known good 5V supply (your adapter).

If they both are power supplied, and have ground connected then what would you need the 5V connection for? Some devices that externally supply power can come with a protection diode to prevent looping power back to prevent the scenario you described but looks like that’s not needed. You would have to know the protocol used such as baudrate, bitlength, stopbits and parity. If you don’t have that info try common baudrates (115200), 8 bits, 1 stop, no parity.
