If you have a Pentium 4 computer and you are experiencing any issues you may need to update your headset to the latest firmware.
Obtain the latest Firmware off our website. It is the FW-Updater that is needed.
A work-around is to use a self-powered hub to plug the headset into. Since several popular hubs have been shown to be ineffctive at resolving this issue, please contact Plantronics to obtain a list of hubs that are known to work. Installing a PCI-USB card will also usually resolve this issue.
