I have had this Griffin 'iMate' adapter for a while now. It's a nifty little cable that adapts Apple Desktop Bus devices to USB. So, for example, it lets me use my Apple Extended Keyboard II and ADB mouse I on a computer that uses USB. Now, I assume that it's true that ADB is NOT plug-n'-play. In fact, Apple claimed, in their old user manuals for computers, that removing an ADB connection from the Apple computer, while it was on, could damage the peripheral or ADB port. My question is: I know USB is plug-n'-play, but is the ADB device connected to it suddenly plug-n'-play capable once adapted to USB? I am wondering if the sudden plugging-in and unplugging of this adapter, with an ADB device connected to it, can damage the ADB device. I don't know if this was a coincidence, but I used my Apple Extended Keyboard II on a newer Mac and unplugged it/plugged it in freely without worry. At some point I did get odd issues, such as the caps lock light sometimes not turning on when I pressed the key, or turning on only once the key was deactivated, requiring some toying with the key to get it to be in-sync again. Also, about two or three keys on the keyboard are now screwed up. I can't quite remember, but I think when I press the 'W' key, 'wx' gets typed as if I pressed those two keys in unison. Did this iMate, with its questionable architecture, do something to my keyboard? I wanted to plug in my original Apple Extended Keyboard I to a newer Apple computer, but I am afraid to after what happened to my AEK II. Any ideas? I am just a little skeptical on the safety of this device. As for the mouse, no problems occurred. (not much can go wrong with a mouse).
