If there's no chip talking host on the end of that electricity no driver will fix that.

So to those of you who are mourning the missing OTG/host mode, what were your day-to-day use cases where you needed them? What were you doing with your previous tablets and host mode?
The second USB peripheral I use quite often is an USB2Serial, for serial console, device control and connecting some ancient landline modems I have to use (yes, there are places on Earth where that is your only connectivity
).

Well, at least Mini A/B/AB ports have exactly the same wiring and electrical specs. The main difference is the form factor and that devices with AB ports have to support host/device auto detection via electrical resistance on pin 4.
So with a custom (non-standard) USB cable AND proper software/driver support pretty much any device with a mini USB A port a can act as a USB host.
Only limitation is, that power supply for connected USB devices is not guaranteed and you have no auto/host detection.
So I don't see why this shouldn't work with the N900, even if this means building a custom adapter (AB port on one end, A on the other).
Of course software support is then another thing.

You can't connect a camera in host mode, but the N900 comes with a good camera. The use case is still relevant but is not as heavy as in previous Maemo devices.

USB OTG is in our radar for future releases, yes. Too soon to make an official commitment though.

Well, sir, I thought about it. I'm keeping my pre-order because the N900 seems so useful. It's very nearly the phone I've wanted for at least five years.
I'll find a way to copy my pictures into it when I travel.
- The cafe solution has charm. A USB flash dongle isn't that expensive or heavy.
- Carrying an N800 doubles the weight of the computing devices but allows me to copy pictures and lend a computer to a friend.

Serial Bluetooth....

Carman relies on a serial bluetooth for it's data so that's definately do-able

I have been thinking why the N900 might be different beast than the N8x0 in regards to USB host mode. One reason may be the fact that the N900 charges from the USB port. If you think about this: When you turn on host mode you turn on +5V supply to inject power to the USB +5V line. This is the same line than the battery charger takes its input power... so what may happen that by enabling host mode you also make the N900 think it is connected to a charger, which obviously is not the case.
Of course there may/can be a workaround for this, such as a status signal from USB host hardware telling charger not to turn on if host mode was selected, but I'm wondering if the N900 was designed with that in mind...
Other than that, I'm pretty sure the USB controller inside N900 does support OTG, but hardware limitations (like my example) may be the reason host functionality has been permanently disabled.
Of course just a speculation on my part. I do not have any information about the N900 hardware design.

to be sincere, this missing feature turned a light off in my head.. a once-in-a-long-time money sacrifice (for a student 600€ is much for just a "phone"/toy) simply because it could do so much more; I was looking forward to attach it to my ethernet modem, pass on it photos from my (good) digital camera, to attach it to my 1 TB external HD, to attach USB flash drives at it, and who knows what more.
now that money may stay in my pocket for a year or two more...
way early to say "i'll buy it" or not, i would probably wait a month anyway, but in the cases of the N97 and Omnia HD, it were some slight missing features which discouraged the purchase (hw power & qwerty keyb; at the time Maemo couldn't phone, now I'd add the OS).
probably it's a feeling more people share, for the moment it's still early, lets see how it evolves... anyway it wasn't smart to mention that "5 step plan" from Nokia IMO, and to let people speculate about USB host/OTG for quite some time without an earlier official denial (still don't know how official it is (if)).
now, looking at that hardware microUSB port, anybody expert about this stuff? what I ask myself is what's the phisical difference between the N810 port and the N900 port, apart from the "N900 power-in thing". If a ad-hoc cable and software can change the situation, this whole discussion is pretty pointless. The previous tablets needed some hacking too, and ad-hoc cables would soon appear in online Chinese shops...
(maybe we need one of the N900 hardware designers, or the final probuct in some expert's hands.. :/)
of the so far proposed alternatives none is as good IMO, especially the extra 100+ $/€ solutions....
and thanks for this whole discussion; better now than too late.
