Ok, first off, I am at work so I can't check what my husband is telling me
but I know I tried this yesterday & had the same problem. We have two Nikon SB24s on stands with PW IIs synced with cables, then we have my 580 EXII on camera with another PW II connected to my camera (5D MKII) with the sync cable. We can NOT get the flashes to fire with my 580EXII on camera (except for the 580EX II), but if I take it off & attach the PW II to the hotshoe, then all the flashes will fire. We tried having the 580EXII in both M and ETTL. Ummm, can't think what else now I need to add as far as settings but can check when I get home. Any ideas? Thanks!
We had the sync cable going from the PW to the FLASH not to the CAMERA. Once I connected it to the camera, everything works! Sorry for the senseless babble!
