It's just the whole musb-core gets confused with vbus applied when it shouldn't, so we have some issues with switching speeds, entering/leaving hostmode, *not* entering peripheral mode, etc. Also, as we need to stop bme, there's not charging during hostmode for now. All this doesn't mean you could break anything - you CAN NOT, as long as you're not using overvoltaged external PSU or other obviously rogue evil crap

I said "enjoy hostmode" - I meant it like that :-) Don't worry!

Oh I didn't really mean to sound worried. Worst come to worse I buy a new N900 (tired of the crack in my touch screen anyway :P). More so its a worrying affair when the phone simply shuts off and screen fades out.

<Just some suggestions for an FAQ type thing:>
Also, suppose I grab a powered USB host, the current GUI will NOT allow a USB mouse and a USB HDD at the same time.. yes? Due to having to choose a set speed? Will this be resolveable, your post says a 'might' in regards to speed detection, but will that mean multiple device support? also what is the probability of automatic detection? And as an end target, a simple auto-recognize like the N800 has (plug in charger -> charges, plug in usb stick -> mounts, plug in mouse -> sets up mouse) will ever be possible?

Hmm... I need to find a Y cable with mini + regular out to female regular. Then just need a 5v battery pack and anything would be possible with the one cable.

Code:
mini ----------------------
                          |--------- Female USB
5v battery pack -----------
