Hoping someone can point in the right direction...
Camera: A560
Firmware: 1.0a
I have installed both the latest CHDK (0.9.9-1196) and the latest CHDK-DE (1.1.0-677). I have installed libusb-win32-1.2.4, ptpCamGui 2.0.99 with its bundled ptpcam, and ptpchdk-r57-win32. The latest version of all of these tools. And, as expected, camera behavior is identical.
However, there are problems. I can Shutdown and Reboot without problem. However, I am unable to use any button on the camera or in the interface. Although I am not sure this should work since the A560 is a VxWorks rather than a DryOS based camera, once I execute the command:
luar post_levent_to_ui(4484)
Then the buttons are usable. But, other commands (such as switching modes, zooming, or timelapse) loop forever performing the command:
luar get_mode()
