Everything works with a powered hub now. Just an update on my previous post where I was having trouble getting the N800 to recognize a powered external HDD and Flip video device. Got an i-rocks 4100 hub from newegg for 10.99 US shipped, and everything now is recognized just fine using the SW host mode switching. Can't play movies directly from the HDD on the go as I need to plug in, but easy enough to use a 2gb flash drive as a go-between.
