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

Re: N800 USB Host Mode Experiment
 

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.
Pic of the internals of this cable:

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

Re: N800 USB Host Mode Experiment
 

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.

Re: N800 USB Host Mode Experiment
 

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

Re: N800 USB Host Mode Experiment
 

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

Re: N800 USB Host Mode Experiment
 

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

edit: also HP's usb keyboard worked. :D

Re: N800 USB Host Mode Experiment
 

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

Re: N800 USB Host Mode Experiment
 

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.
