Troubleshooting 

When encountering trouble or question, you should reference to this section first. 

If you cannot find any piece of applicable information here or taking a suggested 

action does not solve the problem, contact your retailer. 

Troubleshooting 

Condition 

Cause and measure 

USB port of a PC is unusable 

There is no [Universal Serial Bus Controllers] in the category of 

[Control Panel]-[System]-[Device Manager]. 

It may be unusable for USB port without BIOS settings. 

BIOS settings is different according to different PC and so that 

you should reference to the manual of the PC being used. 

"Unknown Device" is registered 

with device manager (Win98/Me) 

The cause is incorrect operation such as canceling the wizard by 

mistake when connecting with a module. 

Follow the following procedure to delete unknown device. 

Start device manager, select [Unknown Device] and then click 

on [Delete] button. 

"USB Device" is registered with 

device manager (Windows 2000) 

The cause is incorrect operation such as canceling the wizard by 

mistake when connecting with a module. 

Follow the following procedure to delete unknown device. 

Start device manager, select [USB Device] and then right-click 

[Delete]. 

The menu can not be displayed 

when a PC disk is being set. 

Select "Run..." form Start menu, and then type   

X: AUTORUN.EXE (X: disk drive), finally, click on OK button. 

The message of "HI-SPEED USB 

Device Plugged into non-HI-

SPEED USB HUB" is displayed on 

Windows XP. 

This USB module corresponds to communication with 

HighSpeed (480Mbps), and Full Speed (12Mbps) is used to 

communicate when host controller and HUT device do not 

correspond to HighSpeed. 

Warning message will be displayed on Windows XP and it does 

not disturb the operation.
