What I have done here is take a 4 port USB 2.0 HUB and replaced it's non-OTG Male-A cable with an OTG mini-B. It is a sweet N800 USB hub now. I just plug it in and N800 OS2008 host mode is triggered. I can plug in all sorts of USB devices, which work.

I have successfully used this set-up (see photos) with SanDisk Cruser memory stick/jump drive, a USB Compact Flash, Smart Media, MMC reader, a USB keyboard. Note: Each device worked in the hub fine (without power) so long as the N800 wasn't asked for too much juice. To use the keyboard, USB card reader and Cruzer jump drive simultaneously the hub needed to be powered using the supply in the photos.

Thanks...

Great Work!
That is exactly what I want for a long time since I bought Nokia N800. Could you tell it in detail how to make this sweet equipment for N800? A circuit diagram will be very helpful.


Thanks!

The circuit wiring is a no brainer. It is described in many places on this site and on the Internet. Basically you tie pins 4 and 5 together on the Mini-B USB plug and wire 1,2,3,4 to the hub's Printed Circuit Board just as it is were a Female A receptacle. The hub gets +5V from a wall wort (see photo above).

EDIT: I got this all working with an external Hard Disk Drive today. See it here:

Also, here is a little pigtail I made: (pins are 1 to 1, 2 to 2, 3 to 3, 4 to 4, with 4 & 5 on the mini-B tied together). It can be used for low power USB peripherals like keyboards and flash memory sticks.

Would there be any issues just connecting an unmodified USB hub to your pigtail adapter? Seems like you can buy these OTG minib to female usb A adapters.. Someone suggested directron.. and I found this other link:
