By setting MXM to different "limits" I find, arbitrarily, that the Xbox has a limit of 7 controllers, and as I change the number the "MU_7" will change to whatever limit I set (except for

- So if I limit it to 4, for example, I get "MU_4", while 6 gives a report of "MU_6"
I'm wondering if the memory cards resort through names... i.e. the last card is always MU_7, and the next plugged in causes the previous to change to MU_6 and the new one to MU_7.
So M$ cards also report MU_7... that fits my theory, at least. I may have it generate a slightly different report in an update tonight (reporting all drives paths on a memory card insertion).
