Mods please don't delete if this doesn't encourage discussion please let me know how I can frame this to do so... I purchased a new 13.3" stealth and core yesterday and set them up today. Upon getting everything up and running I noticed when trying to use the system that the mouse and keyboard that are plugged into the core would intermittently stop working. Support said I should use less I/O over the core thunderbolt connection. Has anyone found a workable solution to using the cores usb ports?
