Review on Gearmo 4-Port USB to Serial RS232 Adapter with FTDI Chipset, Compatible with Windows 10, 8, 7, XP, Linux, Mac - Enhanced ESD and Surge Protection by Daniel Mettler

The CD that came with the device had a huge selection of operating systems and it contained my coveted Windows 7. But by following the instructions closely I couldn't get the FTDI driver to work. The email response from the manufacturer and the YouTube video link narrated by the Scot looked good, but it was for Windows 10 and it didn't solve my problem either. So I spent $40 on something that after a few days of effort doesn't work at all.
