Hi,
I have connected my usb gps to a WL-500GP router then connected the router to the psp through the router internal serial port, and by redirecting the information I was able to get Mapthis working.
My problem is that the psp serial uses 2,5v and the router serial port 3,3v, should I put a power regulator between the router Tx --- Rx PSP connection ?
Thanks.
PS: I have also been able to port usbhostfs to work with the router so soon I will make a post with all the info about this project ;)
