    And... I finally was able to find a picture of it. A nice one with hi-res.

    It uses a FT245RL which is a USB to parallel converter. You can still get drivers for that for modern windows.

    Follow this link to the manufacturer's page FT245RL (NRND) - FTDI (ftdichip.com) and then follow the driver links. You will want the D2XX drivers and not the VCP drivers.

    Here's a link to the picture:

    The USB chip is the one closest to the USB connector.

    Thanks CFavreau, that is correct. For me, the EasyLase (version 1) shows up as USB\VID_0403&PID_DBD0
    The standard FTDI drivers don't automatically work with it, and updating their .inf makes windows drivers signing check unhapy.

    In my case in the device manager I right-clicked the device and chose 'update driver'
    then 'browse my computer for drivers'
    then 'let me pick from a list...'
    then chose 'FTDI' manufacturer under USB devices, and by some amazing luck the 'FT4222 Interface A' from 2016 works. This driver has backward compatibility for the FT245RL, at least on Windows 10.

    For me, this works under the 'netlase' DAC type in this library, using the newer 'jmlaser.dll' driver which supports the various JM Laser-built DACs.
