Thanks. Just a note on my testing. I used a power hub with 3 USB flash
sticks and a USB Ethernet dongle. Also I plugged a unpowered hub into
the powered hub, with its own USB stick. I tried this on snow/pit both
with and without DM_USB.

For mass storage the detection method is different (you now register
drivers which can handle the various interface classes, etc.) but the
effect is intended to be the same. But there may be an error
somewhere.

Simon
