On N810? What happens if you click on host and click on refresh, does
the state change to host even if nothing is plugged in USB? When
I click the state stays to b_idle.

I have usbcontrol installed, and after checking /usr/bin/usbcontrol.py
it does the same thing as I do on the command line.

To check the nokia cable I plugged it from my N810 to my PC
and it worked (I saw the N810 as a usb storage). 

To check for power issue I used a female to female A to plug
N810 ===>nokia cable===>female to female===>host plug of externally
powered USB hub, on this hub as peripherical there's an USB key.

But nothing when I click on host mode. In dmesg:
