This is amazing! Maybe it will be more amazing if I could charge my battery in host mode.
I followed the instructions that @joerg_rw posted, but the script says "STANDBY". I tried to start and kill it several times with no result.
My N900 is connected to a self powered USB HUB. I tried to test if the hub gives any power to the N900. For this purpose I connected the hub to N900 while the N900 was switched off. The result was: screen flash, vibrating and led flashing. This should mean that the HUB gives power, right?
