My new solderable USB plug arrived today, so I set about the permanent repair, such that the keyboard will just have a very short stub of cable, connected to the PC with a USB extension cable 'option' that Apple kindly supplied when I bought the keyboard'
But, once again, No

I'd neven noticed before, but the original USB plug on the keyboard has a notch cut into it. And the female on the USB extension has a ridge that engages in that notch. For some reason, Apple wanted to ensure that the USB extension cable is used only for the keyboard, and nothing else, so they used modified USB connectors. And since the USB plug I've bought is a standard connector with no notch, I can't use the Apple extension cable.

OK, standard USB extension cables are cheap enough, I'll buy one. Or maybe I'll file a notch in the plug so it fits. But it's always just so darned difficult to do anything at all, when it comes to Apple hardware!
