USB Host mode - which of these pages is valid?
Regarding whether N900 will support USB mode or not, I am confused about
due to the statements on the following pages:

http://wiki.maemo.org/USB_host_mode
http://talk.maemo.org/showthread.php?t=31921
http://wiki.maemo.org/N900_Hardware_USB

Can someone clarify?

There are some (one?) hacks around, which seem to make N900 sort of USB host
mode device (I do not know how they exactly work), although officially the
device does not support that (as expressed by Gil Quim).

The device with standard kernel does not support host mode or USB-OTG but
it is possible to configure (hack) working as host mode but .

I discussed with some developers that did the implementation, HW does not
comply with the USB-OTG specification so we can't claim supporting it and for
that reason standard kernel does not have it compiled in nor device does not
have ID pin connected. The device is open, so if you put your own kernel and
configure it working in host mode, you get USB host but that does not
comply any specification.

The http://wiki.maemo.org/N900_Hardware_USB is good description.
The http://wiki.maemo.org/USB_host_mode is aomehow outdated and
mostly talking about N800 and N810. They did not have USB host mode
switched off from kernel driver and with them it was much more easy with
my old usb-otg plugin. Sad that this more elegant solution is not possible in N900.
