First, have you used any other USB devices on the PC?
If so, you may need to install software for the camera before Windows will recognize it.

If not, if you are running Windows 95 or NT, you may not have USB support.
Only Windows 95 version 2.5 "C" has USB support.
For NT4, you need a 3rd party driver.

Next, go to device manager, and see if you have a USB root hub. You may need to expand the system devices branch.

If the hub is not there, start by going into BIOS settings at POST,and enable the USB port under periphials.

You may then need to install drivers for the chipset on the motherboard.

If you need further assistance, add a comment to your question with more details on your PC and camera.

Hi
there are many reseons:
1-Is USb support in BIOS is Enabled.
2- Is There any conflect with other devices. Assigend IRQ with legcy devices wich does not like to share IRQ.
3- Does your BIOS and chipset and OS support USB and which version.
4-Have you update USb drivers. visit
www.usb.org
5-Did you try it in another CPU. to check for hardware proble.such as device cable or media of connection.
6- Do you see USB in device manager as enable.

Good luck

Look carefully in BIOS, I found "Enable USB" in two places. (Tyan Tiger 133 w/VIA chipset) It drove me crazy until I found the second enable.
