IIRC every USB device has a maximum power. If you plug in a device that
exceeds one or more max powers, something in the hub chain gets it's
power cut to avoid overloading the system.

* Try plugging the hub directly into your computer.
* Try plugging the devices directly into your monitor.
* Try both.
* Unplug the USB-powered clothes dryer, if you have one plugged in. :)
