You can stand the unit on either of its sides.
No t e s:
•
•
This hub unit is not guaranteed to work with all USB peripheral devices.
The unit does not include driver software for individual USB devices. In most cases, USB
driver software needs to be installed on the host computer. Refer to the peripheral device’s
instruction manual for further details. (This unit does not require special software to
operate.)
b
•
•
Not all computers and /or operating systems support USB configurations. If you are using
Windows®, the version must be OSR 2.1 or later and have USB support. Check your
computer’s instruction manual to see if you can connect USB devices.
If you connect a keyboard or mouse to the USB connectors and then boot your computer for
the first time, the peripheral devices may not function. First connect the keyboard and mouse
directly to the computer and setup the USB compliant devices.

Troubleshooting
The LED is not lit
•
Turn “on” the power switch. The unit must be “on” to work as a hub for USB
peripheral devices.
The LED is orange
•
•
Check that the USB cables are securely connected to the unit.
Check that the USB port is enabled on the host computer’s basic input/output
system (BIOS). Refer to your computer’s manual to change the port setting.
Individual USB peripheral devices do not work
•
If the connected USB peripheral device uses software, install the software on the host
computer.
•
Turn the unit’s power switch “off” and “on.” If your USB peripheral devices are self-
powered, turn their switches “off” and “on” as well.
•
•
Check that the connectors are secure in their sockets.
Install the latest version of the device driver on your computer. Contact your
device‘s manufacturer for information about the appropriate device driver.
