device.
Make sure the USB device drivers are properly
installed. Refer to your Microsoft Windows
documentation for more information.
If you are using an operating system that does
not support USB, you can still use a USB mouse
and/or USB keyboard. If these devices do not
work, make sure the USB Legacy Emulation item
in HW Setup is set to Enabled.
This feature works only for mouse and keyboard.
Also, note that the mouse and keyboard must be
connected before you boot the computer.
A USB mouse, keyboard, and/or diskette
connected to the Port Replicator via any
connection other than a first tier hub, will not
work until the OS has started.
If problems persist, contact your dealer.
