come on now, there's still stuff scheduled for today. don't be so impatient

since the NDAs apparently have been lifted, i'm sure it's only gonna be a short time before someone tries.

Craves1 hack showed a flat extension 'cable' can be made. If it matters so much to you... why not.

I'm waiting for my *new* mobidapter to try out. (The one I received was horribly faulty).

mobidapter schmobidapter, there's more to plug into usb than sticks

Since developers got n900's at the summit we should expect real info soon.

I think this thread is deviating from the original purpose. I see two camps: people that want to plug something and people replying with different ways of achieving that function (ethernet vs portable ap, usb sticks vs cardreaders and mobidapters and so on)

I think we should stick to the original point: does or does it not allow usb host mode (even limited power or power injection). Leave it up to the ones that care about usb host to use it.

Sorry if I'm a bit slow, but what does this restriction mean in practice? What (if any) USB devices will work with the N900, and which won't?

With my N810, I can connect to my laptop (with the supplied cable), and to memory sticks and a portable USB keyboard (using an OTG cable I got on ebay). Would I be able to do any of these with the N900?

You will be able to read the N900 as a drive on your pc, but you won't be able to read other drives on the N900.

...nor keyboards and whatnot, as is my understanding.

Yeah the distinction is between host vs client mode. If you are plugging the device into something else (e.g. computer) and using it on than something else, it will work fine. On the other hand, if you want the N900 to act as a host--to plug something into N900 and use it on N900--it won't.

Except on the off chance that OTG is supported after all. After reading a lot of this thread, i really think that horse has been dead and beat into the ground and people are now just beating the ground.

One guy who got a N900 demo model has been told on Summit he would not need to worry about USB host mode since it was a software issue. Source.

English translation (used Google Translate; accurate result):

I've tried to install USB control, but that seemed to do nothing (I think it is intended for Maemo 4, was in fact the developer experimental unstable repository).
But during the summit has a Nokia employee told me that I'm not to worry, and USB host mode is indeed possible, it would be a software issue

Please note I'm just journaling this information. I do not know the authenticity.

Here is output of lsusb -v as mentioned by someone in 'please post dmesg' thread.
