I recently bought SGP to use with an ASI 1600 mono cooled camera. For the first couple of evenings it ran perfectly. Then I found it was stalling on downloading an image. Since then it hasn't worked at all. Last night, in desperation, I tried installing the beta version (188.8.131.52) and it worked for a while then did the same thing. The camera works fine with SharpCap and AGP.
I seem to have it working today (touch wood), running without the guide cam or filter wheel connected to the ASI1600 (i.e. the camera is the only thing on the USB chain) and at the lowest USB speed setting.
Have any other users of the ASI1600 got theirs working with SGP and been able to use the two usb ports on the back of the camera to daisy chain other devices? If so, how? Running two cables outside isn't ideal!
