If your USB-A device isn't detected on the Pro Hub Mini, try these steps:

• Test the USB device on another computer to confirm it works.
• Try a different USB-A device in the same port.
• Disconnect and reconnect the hub.
• Check the device's power needs. Connected USB devices should not draw more than 900mA, and the USB-A ports do not support charging or CD drives.

If the problem continues after these steps, submit a support request.
