I am looking for a usb hub that supports what the one I have does not. My issues right now is that I have an external soundcard, two external harddrives, a MIDI-keyboard and a Steelseries mouse. The only thing that works via the hub is the harddrives, but Mavericks doesn't like it when the Mac goes to sleep since it does not know how to safely dismount the drives beforehand. The mouse isnt recognized at all. The hub Im using is from Sandström and has its own power supply. Can't seem to have any drivers either. Any ideas?
