General Windows 98 / ME USB troubleshooting.

Cause:

Below is a listing of general troubleshooting that can be done to fix the majority of USB and USB device issues. If you are unable to resolve your issue reading the below solution ensure that  you have also reviewed our USB Page.

Solution:

Check CMOS

If present, ensure that USB is enabled or set to legacy and is not disabled.

Additional information on CMOS can be found on our CMOS page.

Check Hardware

Verify device works properly by connecting it to another USB port and/or to another computer with USB, if available.

Check Device Manager

Verify that the USB is present in Device Manager and that the root hub is not encountering an IRQ / DMA confliction. Finally, verify that no other devices, including your USB device, is not encountering any conflictions.

Additional information about Device Manager and how to troubleshoot conflictions can be found on our Device Manager page.

Check Cables

There are two available types of USB cables: high and low speed. These cables differ by shielding and plugging a high-speed device into a low-speed cable can cause signal distortion over long distances.

Check Hub

If plugged into a hub, attempt to disconnect from the hub and connect directly to the root hub (directly to the computer).

Check Power

If no devices work when they are plugged into the root hub, verify that the power requirements of the bus are not being exceeded. USB devices may draw a maximum of 500 milliamps per connection. If a device attempts to draw more than this, the specification calls for the ability to disable that specific port until the computer power is cycled (this is called "suspending" the port). In addition, if the device draws less than 50 milliamps, the port never becomes active.
