imac and usb hub not working
My iMac won't recognize anything plugged into my powered usb hub. Its a dynex from Best Buy. Only 2 months old and gets more finicky with time. Nothing of significance power is plugged into it. Have a flash drive and small garmin gps I download info off of. Any suggestions?
iMac (27-inch, Late 2012), OS X Mavericks (10.9.2)
