I've been using SharpCap 4.0.9545 with a ZWO 294 MC Pro in a windows 10 environment trouble free for months. Last week I Disconnected the camera to change a filter, and since then I am unable to get a completed capture. The last page from the log is as follows. If anyone has any thoughts or suggestions, I'd appreciate your help.
best,

Re: Failed Capture with ZWO 294 MC Pro
Hi,
looks like either a camera setting is being remembemered and restored that is causing problems or it is a USB communications issue. An outside chance of a hardware problem with the camera.
First step is to open the camera with <CTRL> held down which will reset all camera settings to defaults.
If that is no help then run through the USB troubleshooting steps described on this page : viewtopic.php?f=18&t=349&p=1556#p1556 ... What you are seeing where the camera is detected and settings can be adjusted but no frames come through is typical of poor USB communication - the simple messages to change a setting or open the camera work fine, but the large amount of data needed to transfer a whole frame in it is much more likely to encounter an error.
Testing on another PC and with an alternate USB cable is a good idea. If all of that *still* gives the problem then you have to start being concerned about a hardware failure in the camera
cheers,
Robin
