PoweredUSB Connection

If you are using CyberData's 4-Port PoweredUSB hub, see the user's guide at the bottom.

Important Note on PoweredUSB Connection:
Always connect the PoweredUSB cable to the PoweredUSB peripheral device before connecting the cable into the hub port. Once the cable is connected to a hub port, it should NEVER be disconnected from the peripheral without first unplugging the hub end of the cable. So also, a printer or peripheral device should NEVER be re-reconnected to the cable without first unplugging the hub end of the cable. Leaving a PoweredUSB cable plugged into a hub port and attempting to disconnect and reconnect at the peripheral's end will cause power damage to the hub. That end of the cable is not hot-pluggable. This is part of the PoweredUSB specification.

To restore or initialize correct operation of a hub:
Please complete the following steps (very important to do them in order):

  1. Make sure there are no devices connected to the four ports on the hub and the hub is unplugged from the PC.
  2. Power the hub using the power brick.
  3. Plug a HID-compliant device, such as a mouse, into the lower portion of one of the 12V PoweredUSB ports on the hub (standard USB portion of the connector).
  4. Connect the standard "A to B" USB cable into the  into the hub B connection.
  5. Connect the A side of the cable to the PC with the OS. Mouse should enumerate on the PC.
  6. Move the mouse around. You should see the cursor move on your screen.
  7. Connect the PoweredUSB cable to the printer.
  8. Connect the other end of the PoweredUSB cable to the hub.
  9. Printer should now enumerate and allow you to load printer drivers on the PC.
  10. At this point the HID compliant mouse can be removed.

If this does not help, please outline the behavior you are experiencing, the troubleshooting steps you have tried, and open a techical support ticket with answers to the following:

  • What is the OS of the computer you are using?
  • What are the make/models of the devices you are plugging into the hub?
  • How are you supplying power to the hub?
  • How do the indicator lights on the device behave?
