i read this thread and see different thing , usb host mode can't be enable due to an hardware limitation and other way that is a software problem.

i have an archos with usb host enable and with extenal HDD i must use an external alimentation +5v , so does anybody has try to plug not an usb thumbs but an extenal HDD or SDcard reader (with external power) on the N900 and check if usb mode is enable ??

or is there a external way ? have a bluetooth-To-Usbhost adapter ?
