Sorry for the delay in my reply.
I just plugged it in and tried it. The Keyboard is recognized as a Keyboard HUB. I tried plugging the stick into a USB hub.
The access lamp was on, so I was able to confirm that the power was coming on.
However, the USB stick was not responding to Disk Utility either.
This keyboard doesn't seem to function as a hub either. However, I was able to confirm that the power was coming on.
Since MagicKeyboard does not have a USB terminal, is it recognized as a keyboard? ?
If so, if I peel off the back of this keyboard and disconnect the USB wire, will it be recognized as a Keyboard?
I found a video on Youtube that shows how to disassemble and clean the A1243 keyboard.
It seems difficult for me because I don't have enough skills.
