Will this one do?

I can knife the plastic and solder points 4 and 5.

I contacted pc-mobile which is a hong kong based cable store that I know from experience has a lot fo cusotm cables found nowhere else. I got a reply, and even though they dont have the exact cable we need - its not far from it:

this should work fine for manual USB OTG

This is a USB mini B extension cable, and should be perfect for making a auto-usbotg cable. The reason for that is that this one actually has very easily accessible cables, compared to the other 3 cables i pryed open earlier today. I actually already had one of these from pc-mobile, and am currently waiting for a PM reply from Master of Gizmo regarding color coding.

Should be easier than opening and soldering those tiny connectors
Extension cable is here: http://pc-mobile.net/pspgps.htm named CMUE

Can someone who has made the cable possible take a picture of the back side and label the pin numbers. I would like to make a cable or two and need to make sure i know which is pin 4 and 5.

Thanks
Dave

So, it looks to me that black should be connected to blue, the rest map 1-1, and the orange wire is the extra sense wire that needs to be connected to something (ground?) to tell the device to go into host mode.

Actually, google and master of gizmo both suggested that the wires are exact opposite of what they should be....after googling some more, i found this had to be true:

According to those two pics, my cable is indeed reversed - so master of gizmo's connectionn scheme that i got is right:
usb-a - usb-mini-b
red - blue
white - green
green - white
black - red/yellow

You must short red and yellow wires on mini-A and connect to black wire.

There... hopefully it will work, wont know until i get the n800

horay! it works !
I made with soldering 4-5 pins together.
and with usbmemory stick, (n800 os2008)

edit: also HP's usb keyboard worked.

So whats the proper wiring and what parts did you use? Any software or hacks needed?

found mini usb labeled B on plastics, and cut all plastics away.
inside it was just like this

then I cut USB extension and leaved female A connector, soldered together like wiring diagram:

thats it, no software hacks at all.

edit: it was second mini usb connector which I "exploded", first one was from sony camera cable, that fourth pin wasn't in back of connector.
