SYMPTOMS

When you plug a Universal Serial Bus (USB) device into the USB port on your computer, the device may not be detected by Microsoft Windows 98.

CAUSE

This behavior can occur if USB support is not enabled on your computer.

RESOLUTION

To resolve this issue, check the status of the USB components in Device Manager. To do this, follow these steps:

  1. Click Start, point to Settings, and then click Control Panel.
  2. Double-click System.
  3. Click the Device Manager tab.
  4. Click the PLUS SIGN (+) beside Universal Serial Bus Controller to expand the branch.

    If Universal Serial Bus Controller is not listed in Device Manager, USB support may not be enabled in your computer's BIOS. Contact your computer manufacturer for instructions on how to enable USB support on your computer.
  5. Under Universal Serial Bus Controller, you should see the following components:

    • PCI to USB Universal Host Controller
    • USB Root Hub


    If a problem exists with a component or device, the device is listed with a symbol indicating the nature of the problem.

    A black exclamation point (!) on a yellow field indicates the device is in a problem state. A device in a problem state is not functioning. A problem code explaining the problem is displayed for the device.

    A red "X" indicates a disabled device. A disabled device is a device that is physically present in the system and consuming resources, but does not have a protected-mode driver loaded.

    A blue "i" on a white field indicates the resource settings for the device were manually selected. It does not indicate a problem state or disabled device.
