When Rock Band ships next month, you'll quickly realize there aren't enough USB slots on Xbox 360 to accommodate the load of peripherals that need to be jacked in for the whole experience. Given that the older versions of the PlayStation 3 feature four accommodating USB ports, this extra step won't be necessary there.
"We were recently shipped the finalized Rock Band peripherals, including the USB hub. We haven't had enough time with the hub to determine how well it holds up -- up until now, we've been using a separate hub that was delivered with an earlier version of the game, but isn't part of the bundle on Xbox 360 -- but we can't say we're happy about having yet another device that needs to plug into the wall, especially considering the hub's limited length.
The hub's made by a company called ViPowER, and while it's a little disheartening there don't seem to be many reviews of the other USB hubs they make, here's hoping we don't have to search out our own replacement hubs a few weeks after launch."
