Writing drivers to support the above may be a solution to the whole usb host mode problem.
While that device has repeatedly been put forth as a solution in this thread, it is not one, unfortunately. It only looks like a solution because the device reviewer was terribly confused. I've posted the following previously:

If the N900 had a working host mode, that "Inspector Gadget" device could provide it additional USB ports and another Bluetooth radio. That's it. Sadly, the device is not the mythical wireless USB hub for which everyone keeps hoping.

Second, even if it existed it would still need drivers. Will it support the N900 and linux in general, maybe, maybe not?
And third even the fastest current BT implementation is just 3mbit/s, that is a third of USB 1.1 speeds. So it would be way to slow for a DVB-T USB dongle (my personal goal), that requires USB 2.0 speeds in most cases, depending on the transmitted bitrates.
So no, it isn't an option for my goals

That's just another USB hub with a built-in Bluetooth dongle though. Like the Inspector Gadget one, it adds additional USB ports and a Bluetooth radio to a PC, but it doesn't help the N900.

USB host mode on Motorola Droid. Droid uses OMAP3430 just like the N900, I wonder if it's impossible to do with the N900 after all?

Beginning to wonder if I should have bought a Droid instead of fighting to big up the N900 to all my mates.... USB host : Droid 1, N900 Nil :-(

Could it be so hard for nokia getting it ALL right for once at least???
Stupid droids are indeed badly built and run a dumbed linux... but still they're pretty slim and have OTG:mad:

I hope they get it right at least with the N9-10-20, it would be about time!

I have both and, believe me, you made the right choice.

I know many smarter people than I have looked at this issue, but could

Possibly be of any use. Reading the article as a layman it seems as though the Droid suffered from the same HW limitation.

EDIT: Never mind AS I posted this, someone else already did.

Thought this might be a fun picture for you all.

Here I am copying files between my N900 and a 250GB HD via USB, using equipment that is both lightweight and very portable. The worst part is the cables. I need to get shorter and less bulky ones.

The hard drive obviously needs power injection in order to spin up. The N900, sadly, also needs power injection. It won't go into USB mode without enough power to start charging from USB. :( :mad: (I tested with just the N900 and N800, it wouldn't work without the batteries.)

Thankfully, the 4 AA rechargable batteries have enough juice to power both the HD and the N900 through the power injection cable.

The N800's file manager shows both the hard drive and the N900's file systems.

Wait, are you using the n800 as a bridge or do you have the n900 in host mode?
