#923 Canon 600D - autoexposure error - PTP errorcode 0x2019


Canon 600D: Lets say I have the Exposure Dial in P mode and try to change it to AV I get the following error:
gphoto2-2.5.0/gphoto2$ env LANG=C gphoto2 --debug --debug-logfile=autoexposure_debug.txt --set-config capture=on --set-config-index autoexposuremode=2

*** Error ***
The property 'Canon Auto Exposure Mode' / 0xd105 was not set, PTP errorcode 0x2019.

*** Error ***
Failed to set new configuration value 2 for configuration entry autoexposuremode.
*** Error (-110: 'I/O in progress') ***

On my Canon 40D I get no error.

This error is seen before in: http://sourceforge.net/mailarchive/forum.php?thread_name=20120405105430.GA16502%40suse.de&forum_name=gphoto-user

Is this a limitation in the Canon 600D firmware or is this a gphoto bug?

    this change ability might not be available in lower range EOS cameras.

    The 2019 code means DeviceBusy, but this might not mean anyuthing :/

    You might be right Marcus. Just tested this on my Canon 7D and no errormessage on that one.

    I get same error with 650D. But with 550D it works fine.
