I do not mean the usbhostfs. Because PSP should be a USB client in that situation
E.g. USB GPS or USB Camera driver

Actually, i can not find any specification about PSP whether is a USB OTG or a USB client only. But i think if PSP could control a GPS , camera. It should be equipped a OTG USB chip.

There are no functions in the firmware to allow the PSP to act as a host. The devices for use with it are specially made for the PSP (and are written to work exactly how the PSP requires them to work. Not in a standard host-client system).

Could you tell me how they implement a camera with psp?
As i remember in USB connection, there must be a host to take over the bus control. Do you mean both hardware and software in psp break the rule of thumb?

But anyway, Is there any examples that i can follow?

Not possible as far as anyone knows. The camera is the host. See
