USB Hubs that work for me:        Belkin    F5U700-blk         – 7 port hub

The 7 port hub had trouble powering high power devices (Alpha WiFi adapter).


Hi Bill, I appreciate your responses, but when I look up these devices I don't see any evidence that they are externally powered.  Have you been able to use the USB-*OTG* port on the Tobi without an externally powered HUB?

Hi Bill, ok, I do see that in one of the later pictures on the newegg site, there's a port for power and a power supply with the 4-port hub you listed.  So as best as I can tell,

The both USB-HOST and USB-OTG ports seem to require a hub to get them to do anything (at least with the devices I've tested.)  And in addition, the USB-OTG port doesn't provide 5v power so to use the USB-OTG port requires not just a hub, but an externally powered hub.

Does this jive with other folks understanding?

Thanks,

Curt.
