[QUOTE="chscag, post: 1786665, member: 46727"] MIDI keyboards draw quite a bit of power and probably should not be plugged into the USB ports on a MacBook or MacBook Pro. You may be able to use it plugged into the USB ports on a late model iMac since those ports provide more power. Charging your iPhone thru the USB ports on your MacBook Pro should be OK. You may have damaged the USB power distribution for your MacBook Pro. Since you provided us with no specs for your MacBook Pro we can't really suggest a fix. [/QUOTE]
