I needed these for work as I have a pile of USB to serial adapters that do not work for whatever reason probably drivers. This works. I did have to use the supplied drivers on CD to 2012 servers but this is a improvement from the others I have bought. Recommended.

Bought to replace two port serial PCE card. I had problems getting Windows XP under VMWaare under Windos to recognize card serial ports for an old Singer Monogramming sewing machine. Gearmo 2 Port USB to Serial Professional Adapter works perfectly. Mission accomplished!

It installed and worked with no problems with Windows 10 controlling a HF radio.

No problems with it, it uses a genuine FTDI chip and can indeed control two RS-232 COM ports at once
