On a USB hub, this means the hub has to have it's own external power supply, typically a wall-wart. The ports on your computer are typically powered and should be able to power a 200 mA device with no problem. If this is a tiny hub used with a laptop, see if you can find one that has a battery bay. -- "Where am I, and what am I doing in this handbasket?"
