Works with Win10 and with a virtual machine
Card installed to use an old software running Windows98 and using a dongle. This key does not work with parallel port to USB adapters. Windows98 works with VMware-workstation-full-10.0.7 which contains VMware-player-10. VMware-player is free and recognizes the StarTech.com PEX1P card and Windows98 uses its standard parallel port drivers.
Everything works in Windows 10.
The Chipset is the OXPCIe from Oxford Semiconductor. I was able to find the drivers for Windows 10 on the Internet.
