@christian1 I had a few minutes, so made a quick port for you.
No idea if it works (very likely it does not, at least not fully) as I don't have one of these devices. But it may give you a head start:

Install as a user driver, change the driver on one of the shutter devices to this driver, save, click Configure, test it out.
