Find another one that is dead from another cause and swap out the ADB Controller for the one you likely zapped.

This is the first report I've ever heard of such zappage, but that's the reason for NOT hot plugging ADB. You've got expeience to gain and little to lose if someone else has a parts MoBo to send or we can figure out which IC(s) you need removed from one and then even the shipping will be reduced to a postage stamp or two.

Anybody got a DOA SE board and a desoldering iron? }
