Query: Not so hot.

This thing does its job sometimes, but for laptop users that are constantly disconnecting, reconnecting, going into sleep mode, etc, it often gets confused. I found myself constantly unplugging and plugging devices back in to get them to be recognized, because this hub seemed to lose the connection. I now have a small travel usb hub that doesn't even require a power adapter and works perfect! Maybe I'll use this hub for a desktop or something that doesn't need to be constantly disconnected and re-connected.
