maemo.org - Talk - N800 USB Host Mode Experiment

How about one of the following solutions from Maplins ?
http://www.maplin.co.uk/Search.aspx?...L16BT&DOY=5m12

In particular the L16BT - USB A(F)-5pin(M) Adp

Ditto from maplins in the UK. Quick and easy, and combined with a cheap roll-up keyboard (yay aldi!), a damn sight cheaper than a new BT keyboard :)

following on my previous post, did you find a gender changer that also does the slave-master USB switching?

thanks

It looks good, but is not wired correctly to make mode autoswitching work.

Re: N800 USB Host Mode Experiment

I have built the required cable. See http://www.harbaum.org/till/n800_usb for details.

BTW: I have switched the my forum view to some simple theme and the simple theme is missing lots of buttons e.g. the one to return to the more complex themes which would have allowed me to add real links ...

I got 2 from Maplin last week a "USB A F-F" and "Mini-USB to A F" adpt. both work but they are not auto sensing so you have to manually edit the mode file.

as BOFH stated, these aren't auto-sensing. I don't believe a USB gender-bender can be as they're 4 pin, not the pre-requisite 5 pin. Maplin sell mini-usb plugs for those who like soldering (or 'soddering' for all american readers :p ) but these are also only 4 pin :(

But it should be easy to write a .desktop file to swap between modes, shouldn't it? I'll have a go and post something if I get it to work

Re: N800 USB Host Mode Experiment

thanks for that; I guess a simple desktop applet would be OK in lieue of auto-switching. I can't believe that Nokia didn't learn from the 770 to put in the right connector - the Sharp Zaurus 1000,3x00 and 6000 were all done "properly"- earlier versions couldn't have done host mode anyway - I've gently pushed my zaurus host connector into the n800 port and I could imagine that the adaptor could be gently hammered and dremelled to fit!

Re: N800 USB Host Mode Experiment

Has anybody tried the Flasher options:

Quote:

--enable-usb-host-mode Set the device into USB host mode
--disable-usb-host-mode Set the device into USB peripheral mode

After a clean flash of 2008 on my N800, I enabled R&D rebooted and then ran the --enable and got a msg that my N800 is now in HOST mode.

But when it boot (even after a reboot) playing a usb device in did nothing {using a A-miniF adpt (4 pin)}.
The mode file was still idle, anybody know what this does or is it for some factory level mode like the ColdBoot option?

another confirmation :

OS2008 + N800 + custom cable (pin 4 and 5 shorted)

and the N800 switch instantly to Host.

worked with USB drives, Canon A60 camera and compact flash reader.

didn't try any keyboard
