LuaError

Hey guys.

This error continuously happens to me on the CLI version. It occurs after 1-4 captures. Any help on what to do?

Shot  14 pages [1987/h] Workflow: Triggering capture.

No matching device: did you properly connect the camera? Can you connect to it with chdkptp cli?

I tried the following chdkptp command and it seemed to stop the abovementioned error, now I just get the NoneType-error

___> connect
open_camera_dev_usb: ptp_opensession failed 0x2ff
open_camera_dev_usb:usb_ptp_device_reset(): Device or resource busy
usb_ptp_get_device_status(): Device or resource busy

Are you on ubuntu? If so try to kill gphoto before running the connect command
