Are You sure, that Your Y-cable is ok? when I connect device through mine *without* using 3th plug, it act just like normal USB cable. in fact, I don't see any logical reasons, why it shouldn't.
In fact, even *with* 3th plug connected to charger, USB connection should be achievable (unless You cross data pins, but why would You on Y-Cable, that's meant for hostmode?).

I am trying to hack scripts together so the hostmode happens automagically
I edited one of my posts in order to explain the solution I found, can anyone answer the other one, can I know if a cable is plugged into the N900 even though it is plugged into no host due to the shorting of maybe the 4th and 5th pin or something similar?? Thank you

if automatic hostmode was possible, I had shipped it 16 months ago
I:E: N900 has no way to auto-detect a Y-cable or a peripheral with normal cable and F-F-adapter (there's a more theoretical option to detect ID-to-GND short as you find it on A-plugs which don't fit into N900 B-receptacle. This needs pullup on ID though, which by default isn't enabled)

Good to know the theoretical approach is not accessible (well, bad really, but you understand what I mean). I guess then I will only be able to automatically host while using y-cable then, the other hosting will require a button... shame

Hallo Everyone!
I am would like to use nokia n900, as a base for a usb-serial device which needs to be powered at 5V. ftdi driver on windows works good, while on linux on usb attach kernel recognises /dev/ttyUSB0 and /dev/ttyUSB1. Is there any chance and way i can make it workable in a stable way on nokia n900?

Can this be adapted for N9?

I tried connecting a N9 as a client to a N900 running h-e-n. It didn't work. I got the message "unable to connect, no filesystem available". Is it possible to connect the N9 to the N900 like that?
I'll test connecting other flash drives to the N900 once I get my hands on some.
