[EDSDK] How to reset camera after error.

[Crazy_Sage]

Hello, I have following problem when I control camera through EDSDK: if camera fails to shoot after EdsSendCommand, for example if autofocus fails, then it will return "device is busy" error for any subsequent commands. Is there any way to bring camera back to working state except for physically turning it off and on again?

I don't know if anyone can anser that, unless Canon chimes in.

There is always a chance, that someone was working with canon sdk and found answer.

Hello,

I have the same problem.

Do you know how resolve this ?

Thank you for your response.

Eight years later, but I am encountering the exact same issue. A focus-priority capture that fails to focus returns AF_NG (0x8D01) and drops the camera permanently into DEVICE_BUSY with seemingly no software recovery option available. Seems like a pretty critical oversight for a single failed exposure to permanently wedge the camera and require a physical reset of some kind (either disconnecting the USB cable or power-cycling the camera). Would be great to have a solution to this!
