But I do by now: after looking at Figure 2-2 on page 8 of http://www.atmel.com/atmel/acrobat/doc1137.pdf it became clear it couldn't work my way: the hub chip is powered by BUS_POWER of the upstream port. So I bought one of those USB Dual Power Cables and connected it as described on http://wiki.openmoko.org/wiki/Specialized_USB_cables#Buy_a_USB_Y_cable_for_powering_USB_devices_and_charging_the_Freerunner_while_in_host_mode and it works - on the Nexus One! It even gets charged! whooohooo :-D Patch and video available at http://sven.killig.de/android/N1/2.2/usb_host -- unsubscribe: [email protected] website: http://groups.google.com/group/android-kernel
