Correct, power injection I'm assuming will be a must.

I visited yesterday in Nokia Store Helsinki, Finland. I checked the application manager and there was USB control available to install. I don't what that means, but I think it can give us some hope. There was no USB devices available so I didn't test it.

it means, well, nothing. usb control is for n8x0 devices and has no effect on the n900. Not even on the 770.

It's a regular package in the extras-devel repository

http://repository.maemo.org/extras-d.../u/usbcontrol/ ...

all it does is

echo host > /sys/devices/platform/musb_hdrc/mode

...and the like.. unless such 'file' also exists on n900, and works the same way, the usbcontrol wouldn't be much of an use

I'm tempted to get a Mobidapter and use it on my E51 (which is going to be the companion of my future n900, since I have separate sim cards for voice and data). Though, it's quite expensive. And, no used ones on ebay.

EDIT you can get a Mobidapter for about 20 EUR less than Expansys on http://www.roalan.com. Mine is going to cost 40 EUR including VAT and airline shipping.

Hi!

First post for me!

According to Michal Jerz, who have been testing the device (n900) for a couple of weeks it will be possible to use USB host.

Questions to Michal Jerz:
Is it true it has the usb host feature ?
if yes did you try to read some usb memory key with it ?

Answer:
It is not enabled by default, but it's quite easy to enable it. Google for "USB host N810". You can do it the very same way on the N900.

good start of a new week?

Unfortunately, that's not so easy my friend. Read the first post of this thread.

Maybe Michal was generalizing to the n900 what was already known for the n8X0 - but there seem to be some hardware differences which don't allow an easy turning to otg mode.

The thread I assume tto is refering to. Last post atm (the one link leads to):

I'm sorry, I haven't read about it on Maemo.org, and I haven't tested it on the N900 yet. I was using USB host successfully on N800/N810 and that's why I assumed it would be the same on the N900....

But the Maemo.org folks surely are in the know and they can't be wrong... Well, what a pity... it was a very useful feature...

I do have a question and I apologize in advance for the very basic technical terms used in this post.

The TI OMAP3430 used in the N900 is a System on a Chip (SoC), that means everything comes together and you have to live with it, right ? The OMAP3430 does support High Speed USB 2.0 On-The-Go.

How can Nokia modify the OMAP3430 to take that feature out of the N900 ? Is it something easy to do ? I mean like not plugging the "thing" that support USB On-The-Go.
