ports with 5VDC 500 mA (maximum) power for each port. When power

Q: Why won't my USB camera (or other USB device) work through the
USB hub?
A: Make sure the driver for the device is installed on your PC, the
device's power is connected, and the USB hub's AC power adapter is
properly connected. If all three conditions are met and the USB hub
still does not detect the device, disconnect and reconnect the device to
the USB hub.
Q: Why won't the green indicator on the front of the USB hub light?
A: When a connected device attempts to draw more current than the
USB hub can handle, the USB hub automatically cuts off power. Reset
the USB hub by disconnecting and reconnecting the USB device(s).
Q: Can I use the USB hub without its AC adapter?
A: Yes, if you connect it to a low-power consumption device, such as a
mouse, joystick, or keyboard.
