I just tried it with my 580EX on a 5D. This is what I found.

If the diffusion panel is deployed, (that is, extended and flipped down over the lens of the flash) then:

--The control wheel does NOT change the exposure compensation if the flash head is tilted up into any bounce position.

--The control wheel continues to WORK NORMALLY if the flash head is pointing straight ahead and clicked into its normal non-bounce position.

If the diffusion panel is NOT deployed (that is, is hidden in its pocket above the flash lens),

-- The control wheel works in all cases, regardless of the flash head's bounce position.

This was a quick and dirty test and certainly not conclusive of anything. But I did recheck it several times and my 580EX is new and appears to be in working order.
