I was researching this option but I haven't even found a way to load a driver. Besides, if the original driver doesn't work out-of-the-box (which I presume it won't), I am not really able to write/compile wine/Windows driver.
I'm hoping that maybe Remi can chime in on this question.
The software is calling DeviceIoControl() which results in ioctl calls in wine server and ends here: https://github.com/wine-mirror/wine/blob/master/server/fd.c#L2408
To forward the call to device, I would need to modify this function, something in this sense:
One other option to investigate: Write a small Windows/Wine device driver that registers the character device and forwards it to the Unix device node. If you get that working you shouldn't need to modify wineserver in a very device specific way. In theory the API is also stable (Wine just implements the Windows driver API), so the Windows device driver can live out of tree.
See dlls/*.sys for some examples of existing device drivers; In particular mountmgr.sys, wineusb.sys are examples of drivers that talk to both the Windows and Unix side.
