How to find software for Labtec mic

Rifling through drawers and came across a Labtec Mic. I've searched on line for the installation software but can't find it anywhere. It looks like a Labtec 524 but there is no model # on it. Any advice? I tried to update the software but Safari says it can't find a matching app on my system. Not sure which was the right community to post to.

Thanks
