I thought the psp's USB port was only a slave device, which would mean it can only connect to a host (PC etc) and as such is unable to communicate with nor supply power to attached devices.
But it seems to talk and supply power to the new camera/gps attachments so I guess I was wrong.
Having said that, until there's software for the psp to allow either of those things, neither are possible.
So no, you cannot currently attach a USB keyboard or flash drive to your PSP. I wouldnt hold my breath on either.
