demonboy, The problem you don't seem to understand is that what you're trying to do is impossible. You can NOT connect ANY TYPE OF WEBCAM TO THE PSP, EVEN WITH CUSTOM "DRIVERS" (Something the PSP doesn't even HAVE).
The PSP is a USB-Slave. A webcam is a USB-Slave.
You can't connect a slave device to another slave device.
Go plug a hard drive from a computer into another hard drive. Will it do anything? No.
You're essentially trying to do the same thing.
You need to connect a slave device to a USB-Master device, something that the PSP is NOT and can NEVER BE. It has nothing to do with software or custom firmware.
Give up.
