So this issue has cropped up over the past few months. My Apple VGA Multiport USB adaptor doesn't seem to detect any USB 3.0 drives. I insert them and I see them light up (the power is being delivered), but the MacBook doesn't detect it at all. I have to RESTART the laptop in order for it to work. I have 3 USB 3.0 drives and 3 USB 2.0. This issue happens only with the 3.0 drives. The 2.0 ones are detected just fine without a restart. What gives?
