JSI Tip 2954. Connecting a new USB device causes not enough power message?

After you connect a new USB device to a USB hub, you receive:

The hub doesn't have enough power available to operate the <devicename> USB Device. Would you like assistance in solving this problem?

If you click No, the device may not properly function.

If your USB hub is supplying power to the device, you may not have enough power.

To fix the problem, use the A/C adapter that came with your device to power it, or connect an A/C adapter to the USB hub.
