extension cable

[ruspa]

I noticed 2 extern pins out of the unit 290, they make me think that a common mini-usb extension won't do the job. Anyone knows if those two small teeths just around the usb socket are junkie or are (who knows) power supply? I found pictures, even videos of extension cables for psp290 but no pinouts or schematics. If anyone has one, please post since I'm gonna build one right now.

you need one of the pins to power the unit, so regular mini-usb extension cable would not work...
it was explained already - next time please do some searching before you post..

you are right, pity me. Anyway... I've been searching in both electronics and digital equipment stores in my city (40k citizens) and no one has the extension cable for sale, nor the spare male and female jacks to handcraft it. I think I gotta made some kind of Faraday cage below the gps unit :D
