I bought an Orion Nautilus 7x1.25 filter wheel from the CN classifieds last week, and had a lot of trouble getting it working in Win 10 x64. After many hours of fussing with it, I finally got it working and I wanted to leave a note here for future readers since it has been nearly impossible to find recent information about operating this wheel with modern 64-bit Windows.
There have been a few previous threads on this topic here and elsewhere, but I hadn't found any indication that anyone got it working in Win10 x64. To the contrary, many people gave up on it and ditched this wheel for something better supported. The latest driver Orion provides is 32-bit and doesn't work at all in Win10 x64. Orion's lack of support for their own legacy devices is annoying and shameful. It can't be that hard to recompile their own drivers unless.. ::gasp:: their driver development is contracted and they don't have a clue how to maintain it themselves?
Anyways, this discussion in aptforum lead me to 64-bit drivers for the BrightStar Quantum wheel which is apparently the exact same device, just without the Orion brand stamped onto it. That didn't work out of the box though. Both the standard driver and ASCOM driver installed just fine, as did the associated standard and ASCOM efw controller applications, but both were unable to find the filter wheel. I can see it in Device Manager, sitting on COM3 or COM4. Tried different USB ports, different cables, rebooting, forcing driver selection, and various other gyrations, to no avail, at least not for the first 3 or so hours.
I then plugged it into my Linux box, but didn't see any USB device register on the first 2 USB ports I tried. Finally found it on the third USB port. All are USB3, and all are rated for at least half and amp IIRC, so I'm not sure why it only worked on one specific port. I opened Indi/Ekos and loaded the Quantum FW driver and it works great!
That gave me hope that the filter wheel's control interface works, so I went back over to the Win10 laptop and tried each USB port again, this time using a terminal app to try to send commands to the wheel according to protocol noted in the INDI source code here. At each of the first 2 USB ports, I opened the associated port (COM3 or COM4) and tried sending "SN\n\r" command and a few other things but saw no response from the wheel. Then on the third USB port, associated with COM13, I finally got responses from the wheel, and they were sensical. So just like with the linux box, the wheel seems to only work with one of three USB ports.
I then tried the Quantum ASCOM Controller app that came with the BrightStar drivers, but it still couldn't find the wheel. That was using Windows' default generic serial device driver. Finally, I forced the Quantum driver and tried the Quantum ASCOM Controller app again and -- SUCCESS!
Now that I know it works on one USB port, I tried the other two again, forcing the Quantum driver again, but still nothing.. no response in terminal and ASCOM can't find the wheel.
I'll try with a powered hub tomorrow, but I don't expect that to work more any better than my laptop's native high-power USB3 ports.
If this driver gives me any further trouble, I may take a shot at writing my own. It should be straightforward, given the simple command protocol which Indi outlined.
Anyways, I hope this saves some future reader from hours of hassle and potentially giving up on it. I'm still mad at Orion.
Minor update: works well via the USB hub on my asi1600, with the asi1600 plugged into any USB port on the laptop. That's a relief!
