POLAR IrDA USB adapter device driver

[Danie Bosman]

Hi! New to this forum. Sorry if I should be posting elsewhere on this forum. Direct me if I'm wrong.
I managed to get my old Polar S710 Cycling watch/computer going again. I have the HRM strap, cadence meter and speedometer, all working. I also have the white IrDA USB adapter. But I can't find the installation disc for it, with the required device driver.
I have the POLAR Precision Software setup on an old Windows XP PC, but cannot get the IrDA device working, no matter what driver I download (And I have downloaded plenty!).
Can anybody please assist me in finding this driver? I will be very much obligated for assistance regarding this matter.
Regards!

For what it's worth, I got to know about this site, as I saw the same devices that I have, advertised for sale, for R500. When I clicked on the link, unfortunately, they were already sold! And therefore I could not message the seller, to ask if he still has the driver 😞
