Omnis Duo: How can such an expensive device not support multiple USBs?

Guys, it's ridiculous that this thing doesn't support multiple USBs with a hub. I'm ready to return this thing and no one I know wants to buy it for this reason alone - One of the best part of learning to DJ is going b2b with other DJs and this is simply not a usable option on this. And no, no one is going to carry around an SD card. Is it even possible to support this with a firmware update? If not I know a few people including myself that will be returning this soon.
