When running on operating systems such as Windows XP with no devices attached (an empty Hub),
the operating system turns the Hub off. The operating system does not detect non-compliant
peripherals when they are hot-plugged into an empty Hub. Consequently PoweredUSB power is
not supplied to the peripheral. In this case, you can restore correct operation as follows.
1. Unplug the Host side connection for five seconds, and then plug it in again.
2. Be sure that at least one USB device is plugged in when the computer is booted, or leaves
standby mode.
3. Plug in a standard USB compliant device, such as a mouse or keyboard.
4. Disable the low-power, standby operation. With this configuration, power is always supplied to
the PoweredUSB ports regardless of the PC’s operational state. For more information, contact
CyberData as instructed in
