Hi A little while ago when i was testing a setup for my mac, i plugged my mouse and old white apple keyboard (one before the current slim ones) into a USB hub, however i think I plugged the hub in with the wrong power supply and blew the fuse or whatever the is to blow on the keyboard and mouse, now if i connect them to USBs they just dont work. Is this possible to fix? Would be a shame for a good keyboard to go to waste, is it possible if i took it to my local PC store (they fix stuff for people) and see if they can get it fixed? Or no point? Thanks.
