i tried to use Helicon remote with my EOS 550d. Each time i run helicon focus it detects my 550d (i can see informations on the screen) and then informations desappear, only EOS 550d is selected in the combobox.
Live view is not available and i have a message like : timeout ...
then my 550d is stuck even if i turn it off, the SD card led stay light on and i am obliged to disconnect the battery.
i tried 5 or 6 times and now ... my 550d is finally stuck even if i disconnect the battery
Do you know this problem ?
