Troubleshooting

Problem: The hub is installed, but a downstream 
device isn’t working.

Soluton: Some USB devices get their power from the 
USB cable. If you are using the ICI200A without an 
external power supply, it will only provide 100 mA to 
the downstream ports. If your devices need more 
power, connect an external power supply to the 
ICI200A. It will then provide 500 mA to the down-
stream ports.

Problem: Do I need drivers for the hub?

Solution: No, the operating system will detect it and 
install it automatically.

Problem: How can I be sure it has been installed?

Solution: The new hub will be listed in the Device 
Manager.

Troubleshooting (Continued from page 5)

Problem: Can I use USB 1.1 and USB 2.0 devices 
together?

Solution: Yes. USB 2.0 is backwards-compatible with 
USB 1.0 and 1.1.
