Does RoMI/O II work with Windows Vista/7/8.1/10?

There are two different hardware revisions of RoMI/O II: Rev A and Rev B. While revision B works without the installation of any driver under Windows Vista, Windows 7, Windows 8/8.1 and Windows 10, revision A does not work. Which one you have can be identified by checking the rating sticker on the bottom of the unit. The following picture shows the sticker of either version:

The revsion B has Rev B written at the bottom of the sticker. If you are still unsure or if the sticker is not readable or has been removed, the PCB of Rev A and Rev B looks different. While you can see metal like small circles on Rev A on many internal connectors, they are mostly covered in white paint on the PCB of Rev B.

If you use Revision B, our universal ESI MIDI Port driver can also be used.
