Too early to give out instructions, it's still not fully working (needs a PC connection, needs a voltage boost etc...).

The point is: there shouldn't be ANY twl4030 settings, to make hostmode work.
Basically everything accessing twl4030 GAIA is a bug wrt hostmode, no matter if it's the real hostmode or the "fake hostmode" we're talking about here in the past some weeks

as i understand from specs in charge or boost mode for sustaining those functions, some activity on i2c bus is needed.
if NO CHARGE mode why i2c read / writes activity ?. this useless activity drain the precious battery.
i will look closer on specs for a decent reason.

if vbus sensing for mode selection pop-up is needed instead of pulling status of BQ24k vbus sensing from 4030 via interrupt is preferred.

popup usb mode selection is not in bme or mce . what code is doing this selection ?

Was just looking for what this is before you posted.
cat'ing the language files shows that Mass storage mode and PC Suite are in hildon-status-bar-usb, which as far as I know is closed source.

e: as for the actual buttons, they're scripts, in /usr/sbin as I mentioned above.
pcsuite-enable.sh for PC suite mode
osso-usb-mass-storage-enable.sh for Mass storage mode.
Same for disabling them (unplugging), just replace enable with disable.

If you're thinking about executing pcsuite-enable.sh to trick it into host mode it won't work, you have to connect it to a real host till the driver is fixed.

Edit the PC suite one and change the string to host mode or something.
Just add the echo H > command to the end of the pcsuite-enable.sh script (NOT tested, but in theory it SHOULD work)

It's quite useless however, since the 'plug into PC' part is still present, which kind of defeats the purpose, again, till the driver is fixed.

My experience with USB WiFi sticks and the N800 is that they need an external power supply to run.
