EDSDK 2.8 Bulb commands not working with 550D
I am trying a bulb sequence program on my EOS 550D using BulbStart and BulbEnd commands with CANON EDSDK V 2.8
This sequence program is working correctly with my EOS 40D, but does not work with my EOS 550D.
When sent to my 550D, BulbStart and BulbEnd commands always fail returning 0x60 error (Invalid parameter)
I have verified that EOS Utility program is able to send bulb commands to a 550D and I guess that some undocumented EDSDK commands should be called before sending bulb commands to a 550D.
Did anyone experience this problem on a 550D ?
Where you able to find a solution? In my case I'm not able to take a bulb exposure with the T1i, the EDSDK 2.8 keeps throwing a 44313 error. It works fine with the XS, 40D, and 50D. But the T1i throws an error.
