Appendix A: Troubleshooting
This chapter provides solutions to problems that may occur during the installa-
tion and operation of the USB 4-Port Hub. Read the descriptions below to help
solve your problems. If you can’t find an answer here, check the Linksys web-
site at www.linksys.com.
1. I plugged a device or other hub into the USB 4-Port Hub and it doesn’t work.
• Verify that all of your cabling is connected properly.
• Then verify that you are using an operating system that supports USB.
Windows 95 and NT do not support USB, and some versions of UNIX-based
operating systems do not support USB.
• If you are connecting a device into the Hub via a serial-to-USB or parallel-
to-USB converter, make sure that the device does not require any more than
500 mA of power. 500 mA is the maximum a mount of power that a USB
port can supply. Any device that needs more than 500 mA of power cannot
be accessed through a USB port.
2. The computer doesn’t recognize the USB 4-Port Hub or any other USB device.
• The operating system has to support USB. Windows 98, 2000, Millennium,
and XP all support USB.
• The USB ports on your PC may be disabled in the BIOS. Use the BIOS menu
to enable them.
3. When I unplug a device and connect it to a different port on the Hub, the device
is re-detected and I have to reinstall the drivers.
This is normal in most cases. Every time a device is connected to a specific
port on the Hub for the first time, the drivers for that device must be reinstalled.

4. Plug the other end of the USB cable into the PC’s USB port.
The computer’s operating system will install the appropriate driver automat-
ically. You may be asked to supply your original Windows CD installation
files, which include all necessary drivers and files. Linksys does not provide
any drivers.
5. Using additional USB cables, plug your USB peripherals into the Hub.
Then follow the installation instructions that accompanied your USB
devices.
The installation of the USB 4-Port Hub is complete.
