Quite obviously attachment of a device to N900 can not be detected unless N900 is in hostmode.
So any popup requester offering a hostmode option ("host ( docking station )") is rather nonsense.[/COLOR]

joerg you are partially wrong. from your point of view is nonsense because you want only host vanilla , cherry or any host flavor you want
BUT
i want a docking station with 7 usb A receptacle capable to power N900 while is in host mode . I want charge battery because the charging hardware is independent from usb controller

i can write a module doing what i want as appendices to a n900 in plain host mode with all vbus code removed
i don't give up on this
as a proof of concept i post a picture with a ACA with mini A receptacles for data and charger . this device can power and charge a device while this device is in plain host . in fact i don't know if this board can handle otg voltages & states and i don't care

2 month ago i tried on n900 this adapter but F..bme was in place
