%hx is for shorts, not bytes. There is no format specifier for shorts,
so a cast is always needed for these if you want to be strictly
compliant. In practice gcc is smart enough to do the cast
automatically. Same for most cases below.
My suggestion to use %hx was really only for the cases where the
variable is an unsigned short or u16, you can leave all the rest as is.
