For consoles, it was actually the original Xbox that started this trend, using a proprietary physical connector, but with a mostly standard usb protocol, for no other purpose than to be consumer hostile. Physical hacks was of course rapidly found in this case to adapt it to be standard compliant.

Then again, with xbox360/kinect, the camera was using the usb procotol, but microsoft prevented it from working with pcs in windows. Instead you had to buy a several times more expensive "pc" version, that had the same specs, except for having the malicious compliance tech was removed.

I guess nintendo learned from this.

There was no standard USB connector that the original xbox could have used that still had magnetic attachment.
