Re: bulb cannot work

<http://gphoto-software.10949.n7.nabble.com/file/n16661/error1.png> 

This is what happened when I try the code

/gphoto2 --set-config shutterspeed=bulb/

Can u find what's wrong with it?

Thank u,
Xu

(P.S. I tried the second code anyway:

/gphoto2 --set-config eosremoterelease=Immediate --wait-event=30s

and the error messages are like this:
<http://gphoto-software.10949.n7.nabble.com/file/n16661/error2.png> 

<http://gphoto-software.10949.n7.nabble.com/file/n16661/error3.png> 

don't know if it helps)
