General USB troubleshooting
Most USB problems can generally be traced to one of the
following problems:
Problem
Computer stops responding, suggesting a malfunctioning or
incorrectly-configured device.
Solution
1. Check that the device is plugged directly into the computer
(root USB Hub) and not into a secondary hub (external USB
device). If the device is plugged into a secondary hub, unplug
the device from the hub and then plug the device directly into
the root hub.
2. If unsuccessful, restart your computer and try the headset again.
3. If unsuccessful, try connecting the headset to another computer.
If the headset works, it is a problem with your computer. If you
encounter the same issue on the new computer, contact your
supplier.
Problem
When USB connection is plugged in, the computer prompts for a
device driver.
Solution
Check with the manufacturer of the device or with your supplier to
determine if the necessary driver is available.
Problem
Device appears as a duplicate of a device in the Device
manager. The second device may be displayed with an
exclamation point in a yellow circle in device manager. You may
be unable to remove the “ghost” device until you unplug the
parent device.
Solution
Make certain that you have the most up-to-date firmware that
is available for both your computer’s BIOS and each individual
device.
Problem
Signal distortion on the headset is present. This may occur if you
plug a high-speed device into a low-speed cable.
Solution
Verify the entire USB chain is working correctly. Confirm that a
device that requires the ability to draw power from the hub is not
plugged into a non-powered hub. If the hub is a powered hub,
verify that the power supply for that hub is configured properly.
