Ok, I've looked around a bit and haven't seen this answered anywhere.
I know that the maximum number of custom tracks you can load at once is supposedly 600 - (Xbox HD - 200, USB stick - 200, 2nd USB stick - 200)
However are we all assuming this simply because the Xbox only has two USB inputs? What about USB hubs?
In theory if you were to purchase two of these you could have EIGHT flash drives plugged in at once. That's 9 memory units including the Xbox HD itself - 1,800 custom tracks!
I'm currently at just under 400 tracks myself, so nowhere near needing this kind of setup, but I would hate to have to start deleting tracks once I reach 600, so I'm just wondering if this is even possible.
Has anyone out there put this theory to the test? Do any developers know the answer to my question without needing to test it out?
