Actually the thread is USB 2.0 OTG on N810, and if the device requires power you will not get it to work without it.
Besides, you're not exactly right with your statement as the N810 does seem to provide power, just not enough current for all types of devices.
And there's no reason to address the power issue anyway unless I were talking about specific devices and whether or not they need more power. The question of how to boost the current if you need to isn't a mystery. You just need to decide on your own solution. Portable hubs get pretty small, but if that's not small enough get a Y-cable to power the device via a battery pack while it's connected to the N810.
Google will tell you how to build the battery pack and it will also find you the Y-cable you need for a couple bucks.
Or find something like this (though I didn't read through to see if this is specifically what you'd want): http://www.google.com/products?q=%22...&lmode=unknown
You may even be able to find some kind of USB adapter with a built-in battery that does the job. I'd check eBay for these kinds of things that tend to come out of Hong Kong.

Finally ran a quick test on the n810 to see the write/read speeds to my external HD. In short, write 100Megs, 37secs, read 100Megs, 30secs. Only did a single iteration so it's not a very reasonable sample size 
Good enough for what I need. I've been using a vosonic X's drive vp3320 with it's external power supply to do the quick test.
Code:
/media/usb/sdb2 # time dd bs=1M count=100 if=/dev/zero of=test.bin 100+0 records in 100+0 records out real 0m 36.81s user 0m 0.00s sys 0m 4.48s /media/usb/sdb2 # time dd bs=1M count=100 of=/dev/zero if=test.bin 100+0 records in 100+0 records out real 0m 30.75s user 0m 0.02s sys 0m 11.05s /media/usb/sdb2 # /media/usb/sdb2 # ls -hl *bin -rw-r--r-- 1 user root 100.0M Dec 18 12:40 test.bin

this should work, right?

I ran into trouble by setting the host mode enabled in my N810. Now I can't connect to Internet with my phone, but wifi works ok. Can someone please tell me how to disable the host mode (ie. the default value to put to the file that enables host-mode)?

RE: Gender changers -
It seems one of the best present methods for using the N810 w/ stock cable for a USB stick is to use a USB Gender Changer,A Female to A Female.
Every place I found one on the web it seems they wanted exorbitant prices for shipping ($5 and up per PIECE) and on a PIECE basis, not grouped. I did find one place (Directron ) I've dealt with throughout the years that sells them and lets you combine with other orders.
Thus I needed an IDE DVD burner, they had a good price on what I wanted, I ordered two of the gender changers and the burner, total shipping $8. With just 2 gender changers shipping was $7.
And for anyone that would like to take the hassle of buying a bunch of them and selling them back to the community for low shipping costs (which I thought of doing) you can get 10 of them for $25. Right now they are "on sale" for $3@ or 10 for $25.
Note - don't work for Directron, just a satisfied customer.

Is there a list somewhere of the USB modules that the n810 kernel has particularly i am wondering if it has the USB-serial module (it creates a serial interface for USB devices)
Also does the n810 support creating PPP sessions does it have the ppp modules.
If both are true i am hoping i should be able to use after putting the device into USB host and having a powered hub plug in my hsdpa modem and create a connection. I have not yet got a n810 but im seriously looking at it as a replacement to my HTC universal

PPP support is in the kernel, but for USB to Serial adapters you'll need a module compiled for whatever chipset your adapter uses.
Few modules are included out of box, but pretty much any Linux kernel module can be compiled.
There's a guide to kernel and module compilation for the tablets here: http://maemo.org/development/documen...for_maemo.html
and
I would prefer not to haul around an adapter plus a powered hub, I would like to be able to use a minimal battery pack to power a thumb drive.
