I have a DongleBook Pro and I use a powered 7-port USB Hub. Connected to the Hub is a backup drive, an audio interface, an ethernet adapter, and some other stuff. The only device that causes me trouble is the ethernet adapter. For some reason, it won't actually give the computer internet unless I wake up the computer, unplug the adapter, then plug it back in.
Like I said before, the only way to get it to work is to unplug and plug it back in. Any ideas?
