Does the GUI launcher see the files on the flash drive?

Dunno what a GUI launcher is, but file manager launches automatically and i can browse it like the memory cards

At least there seems to be duct tape in the picture!

Does anyone know if for the N800 it uses the sense line like the N810? I.e. if in the mini-B connector, pins 4 and 5 are shorted (instead of 4 being a no-connect) and the chip is in OTG mode if it will automatically switch from peripheral to host?

With my n810, and a powered hub, an iPod is recognized, and will mount if it is a FAT (Windows) format unit. A Mac-native iPod's partition table isn't recognized, nor is hfsplus a stock filesystem.

The files are visible in the filesystem just like any Flash Drive. I suspect if GTKpod was ported it would work too.

tz1: Is the powered hub really necessary for the ipod? I'd think (and hope), having its own battery, it'd be designed to not need power off of the USB port...

Re: N800 USB Host Mode Experiment
 
The (5G video) iPod apparently wants to recharge or something else so asks for more than 200mA. The nano or the flash only might not have these problems. Also note it will ask for the peak power usage, not average or typical. The question is not whether it needs it (and defragging a full FAT 5G will drop the battery to zero on a PC), but what it asks for.

I should try my old 3g (recharges via Firewire) - it might not ask for much from the USB.

It might also be possible - but dangerous - to override the current check.

yes. see my post about a nano keyboard and the maplin adaptor.
