A comment I found last night (I can't find it now) linked this bug to this thread about the regulator driver being broken:
In my testing (-rc4+), it looks like the regulator problem is indeed preventing the USB Ethernet port and the hub that it's attached to from being powered up.
Keshava Munegowda indicated that he would be working on this during the week of April 17, 2011.
