I confirm that on my OS2008 N800 (R&D mode) just after: # echo "host" > /sys/devices/platform/musb_hdrc/mode I could get recognized and working without power injector just using an small USB adaptor: - USB keyboard - Corsair flash voyager 1GB USB key (file manager started automatically) - USD LED lamp :) Kingston TravelLite SD/MMC reader didn't work though: rejected because not enough power according to dmesg. Lacie USB 2"5 external hard drive with power USB on my PC and normal USB on the N800 started the automount process but it was not completed successfully, probably not enough combined juice to power the hard drive. Another great OS2008 news :).
