I have an old iMac keyboard that I use with my raspberry pi. I'm trying to repurpose this keyboard and want to use a wireless mouse dongle with it on a computer with only one usb port. I seem to remember that one of the usb ports is for power only and that one was for power and data. But is it too old to pass data from my very new wireless mouse? Would there be an easy and documented fix to allow a more modern usb data passthrough?
