It's interesting to think about how to do this. Linux is so amazing because this support is:

• Included the Linux 2.4 kernel as part of USB Gadget Driver
• Android includes the drivers so that any Android build can use USB-on-the-Go
• PLX 3380 is a registered compatible 2280 (the USB 2.0 version)
• USB3380EVB is a PCI Express card that allows any Intel Linux system to be a USB Peripheral. $100 pretty cool
