It's possible that a Sharingan genjutsu can work on a Byakugan user, but because of 360 vision, they don't have to actually give direct eye contact with their enemies. Also, it's as I said, the Byakugan can be used to distinguish whether or a foe is real or an illusion by searching the area for another chakra signature, as proven with Hinata against Tobi. Now I'm not saying it can see through all genjutsu, heck even Sharingan can't, but it's quite clear the Byakugan is not useless against genjutsu.
