I think you are misremebering here. I don't think I've ever seen a dongle for use with any proprietary hardware. The only effect they ever had on hardware was for it to not work properly anymore.
The dongles were used for software copy protection. They were small things that you plugged (most often) into the parallel port. They then sat there and did nothing obvious.
Today I'm quite okay with calling anything a dongle that is small, plugs into the usb and doesn't do anything immediately obvious. But maybe that's because I'm a german speaking Swiss. We have a history of misusing a lot of english words.
I have seen (and used) hardware dongles as described, they 'usually' had a different socket on the far side (so were basically an adapter that prevented the hardware being used without it)- however some used what appeared to be a serial output on the other side- one actually caused damage to a machines port as it simply 'swapped' the wires around to different pins- which stopped the machine working without the dongle- however, what it did do was when a standard serial plug was plugged into the dongle by mistake wasnt pretty (user was swapping devices and only had limited number of serial ports available) instead of unplugging the dongle and lead and plugging in new lead, they unplugged the machines lead from the dongle, leaving it in the serial port and plugged the other machine into it instead of the serial port...
Scratch one motherboard for the machines controller....
Company that made the machine that required the dongle eventually paid for the repairs (several thousand dollars) only after legal action was taken against them- and that dongle was glued and heatshrinked to its lead so it could never happen again...
