At that point, the cursor will be frozen on the screen and the caps lock key will not light up when pressed, but the power key still invokes the sleep/restart/shutdown dialog. However, if I then unplug the USB hub from the left side and move it to the right side, one of two things will happen: 1) the right-side port will go to the same state as the left side, with no ability to see devices, even if I switch back to the single device that was connected before, or 2) all keyboard and mouse input will stop - the built-in keyboard and trackpad, and an Apple Bluetooth keyboard and trackpad. Right-side USB: I usually don't use this port, but sometimes I have a tablet connected directly there and it is still working when the problem occurs. When the problem occurs, the display is unaffected. Thunderbolt, next to the power: I have an external display connected with a Mini DisplayPort cable. When I have the Ethernet connected, the Network control panel shows the Thunderbolt Ethernet status as Cable Unplugged. When the problem occurs, the light on the FireWire drive turns on, but the drive doesn't mount and Drive Utility can't see it. I've tried two different FireWire drives and two different FireWire cables. Thunderbolt, next to the USB: I switch between a FireWire 800 drive and an Ethernet cable, connected with Apple's FireWire and Ethernet adapters.

They no longer appear in apps like iTunes or iPhoto, and Xcode and Android Studio can't connect to them.
When the problem occurs, the phones and tablets still receive power through USB, but can no longer sync with the computer. I've tried two different hubs and two different cables going to the hub, but that hasn't helped. Left-side USB: I have 2-4 tablets and phones connected through a powered hub.
At seemingly random times, but at least once a day, the ports become nonfunctional and I have to restart the computer to use them again. I got a new mid-2014 Retina MacBook Pro about a month ago, and am running into a problem with the Thunderbolt and USB ports.
