Brand new STC-7 worked flawlessly on testing (per the manual). However, when I took it from the house to the observatory and performed the exact same installation steps on the observatory computer it failed to show up as an available choice under DL imaging. Ditto the filter wheel. Same USB cable, same Maxim DL version, etc. Anybody know what might "block" the recognition of the STC-7 over USB on a given computer? Same version of Windows 10, similar hardware (I7 processor, 32 GB ram). Other USB CMOS camera working fine (ZWO ASI on a different scope). Unless, of course, their USB driver is interfering? Any experience with ZWO and SBIG USB on the same computer?? Any other ideas??
