[libdc] 1394a card with a 1394b camera

[Danny C. <dc...@me...>]

Hey all. I have a quick question.

If a 1394b camera is plugged into the a 1394a card, the following check 
will return true.

dc1394operation_mode_t mode;
dc1394_video_get_operation_mode(cam.cam, &mode);
if(DC1394_TRUE == cam.cam->bmode_capable  &&(DC1394_OPERATION_MODE_1394B 
== mode))
   return true;

However, when I set the ISO to 800, I will not be able to capture 
frames. The work around is,

If I fail to grab frames
- stop transmission
- set speed to ISO 400
- start transmission

Is there a cleaner check available that will tell me a 1394b camera is 
plugged into a 1394a bus?
thanks,
