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.
Is there any example code for PSP act as a Usb Host
Not possible as far as anyone knows. The camera is the host. See
