Are you trying to make the PSP a USB host? If that's what you're trying to do, I'll tell you now, it's impossible. |

Yup, the device that is connecting to the PSP (e.g. Go Cam) has to be a usb HOST.

Sounds interesting, used with usbhostfs could be very, very useful.
You're probably better looking at computer USB interface code than PSP client code, if I understand correctly. |

Well, modifying a prx won't get you what you want - it isn't a simple hex, or even a hex at all. You'd need to write an entirely new driver, or use the existing usbhostfs on both the host device and the PSP.

| from my understanding usbhostfs is a pc driver that recognizes the psp as a sort of host but not really? how would u recommend doing this? |

I'm sorry, but it's obvious with what you're asking that you're way out of your depth.
However, you'd need to port the driver to the usb host device that you are using.
