Re: Sony PSP gaming system
I’d be the last person you’d ask on Signal Comms 
… but I’d have my suspicion that the PSP (natively) wouldn’t know how to deal with a USB keyboard…?
PS2 & xBox (the controllers use USB signals) are like PCs themselves, the USB is for ‘input’.
Whereas the PSP’s USB is like ‘line out’ sorta like the USB on a digicam or a mobile phone? Like the USB is used to connect to a PC which treats the memcard like a mountable disc.
hmm… how to test if PSP knows what’s going on? Anyone got a PSP wordprocessor?? 
I got a few dissected USB cables that I can rig up with jumper leads, and a USB PC keyboard won’t be too hard to dig up.
