My Retina Macbook Pro's behaviour with USB 3 devices is a bit confusing... I'm not sure if there's a software glitch, if something is wrong with my USB 3 hub, or if it's normal... So usually I have both USB 2 and USB 3 devices plugged into the ports on my 4-port USB 3 hub (all four ports are USB 3 on this hub). But if I restart my computer, any USB 3 devices revert back to USB 2 speed! Turns out that I must unplug any USB 2 devices, and only have USB 3 devices connected to the hub at first. Once the USB 3 hard drive is mounted, I can then plug USB 2 devices into the hub and everything is still at the proper speed. Any ideas on how to fix this? I just want my USB 3 devices to run at 3.0 speed when they're plugged into a 3.0 port. No hassles about plugging everything in in the right order! Thanks!
