One point we haven't addressed is whether Clear-Feature(Halt) also clears the fifo. If it does, we're in trouble again. > If SuperH really can't implement endpoint halts in a usable way > (except for ep0), then the options would seem to be (a) kick in > the "no-stall" protocol option, at least when SuperH is in use, > or (b) just say SuperH can't support FSG. The former sounds a > lot better to me... (a) is a reasonable approach. I'll try to code it up later on. But if SuperH can't halt endpoints other than ep0, I would expect that to limit its uses pretty severely.
