Re: ASCOM Driver "freezing"?

Steve Reilly

Another suggestion worth looking into I hope is your power settings in Windows as I have found that USB connections can be powered off if not active after a period of time. Also check the Device Manager for the USB settings. I have issues with my Starlight Xpress guider not being found if idle too long and have found if I disconnect the cameras and immediately reconnect it brings it back to usable. This is the UltraStar which otherwise works great. Not hijacking the thread but may be the same issue.

There's not enough information to say for sure, but the most likely reason is the serial port hung. Are you using a USB/serial converter on a USB hub with a USB connection to your camera? If so, try moving the mount's USB cable to its own USB port on your computer.

I'm seeing the AP ASCOM driver "not responding" again, multiple times
a night now. Seems the cable replacement was not a permanent fix. Can
someone please help? Can't really automate image capture with this continuing to freeze up.

I just upgraded to the most recent version of the driver and ran it
for a few hours without freeze. Are there any bugfixes in the latest
version that would address this, or is this just happenstance (again)? Any help would be appreciated.
