We've just upgraded some of the machines in our studios to Windows 7 machines (Pro) and everything is going fine except for one thing - the Myriad keyboard. The machines we ended up with were Dell Optiplex machines that do not have PS/2 ports (sign of the times?). We purchased a USB to PS/2 adapter, but when we plug the keyboard into that it doesn't seem to work. The connection is in place however, as the lights appear on the keyboard so they are definitely getting power.
