UPS USB chaining?
Authored by: AIVAS on Feb 10, '04 08:20:49PM

The USB hub in the keyboard is a passive device. It is powered by the computer. It has no power supply of it's own. Therefore the keyboard (and usually the mouse since people usually plug it in to the keyboard) derive their power from this hub. There is little power left. I would recommend not plugging anything into the keyboard hub unless it is a self-powered (active) USB hub.

When selecting a USB hub, chose one that comes with a power adapter.
