[QUOTE="chscag, post: 1102744, member: 46727"] Generally, the keyboard USB ports are for self powered or very low powered devices. I have my Logitech mouse plugged into one and my printer in the other and never overdraw power. However, when attaching my external hard drives or optical drive, I use the main ports. Also, the iPod Classic, Mini, iTouch, iPhone, iPad draw too much power for the keyboard ports. The iPod Nano and Shuffle are OK. If you need more USB ports buy a good powered hub. [/QUOTE]
