In response to a question on the DSLinux forums, would it be possible to modify the MCU to act as a USB host? I understand that a seperate psu would be needed for the +5v but apart from that is there a reason why it couldn't be done, either with a C8051F34x or similar controller.

According to the SiLabs data sheet,

WinterMute is right. USB uses a master/slave architecture and the master is much more complex.
