I'm interested in programming a driver for the PSP, possibly using Nanodesktop (http://visilab.unime.it/~filippo/Nanodesktop/PSP_PSPE/nanodesktop_PSP_PSPE.htm), that will allow access to USB devices -- such as an external hard drive -- through the remote/ serial port. As other non-host USB devices, such as GPS (http://deniska.dcemu.co.uk/simple-slim-gps-hookup-77267.html)have been proven to work through this port, this may be possible. PSP Remote Port- to-USB cables and adapters already exist, such as these PC-Mobile cables (http://pc-mobile.net/pspgps.htm) and these from Moby (http://www.moby.cn/). My understanding is that the remote interface uses an RS-232 protocol, but voltage is limited to 2.5 volts. This would require that the external device be self-powered, or perhaps power could be introduced into the cable somehow, but it should at least allow two-way communication, if not host control.
I wonder if anyone has already started work on such a homebrew driver that will allow USB access through the remote port, and if not, is it because there are technical hurdles that make it impossible? I am new to programming on the PSP and would rather not go trudging down a dead-end alley. On the other hand, this would obviously be a major breakthrough for the PSP.
