USB 3.0 is running parallell to USB 2.0. They are not using the same 
carrier.

Connected to a USB 2.0 port, it shows this:

 ugen1.3:  at usbus1
 uhub4:  on usbus1
 uhub4: MTT could not be enabled
 device_attach: uhub4 attach returned 6

I have not tried it on a USB 3.0 port yet.

It would not really bother me if only the Ethernet worked, but surely it is 
connected to the hub, so will be all or nothing.  Any suggestions?


On a USB 3.0 port on a -CURRENT system (r297315), the hub is recognized 
and works:


  ugen 0.2:  at usbus0
  uhub1:  on usbus0
  uhub1: MTT could not be enabled
  device_attach: uhub1 attach returned 6
  ugen0.3:  at usbus0
  uhub1:  on usbus0
  uhub1: 4 ports with 4 removable, self powered

Are USB 3 hubs not backwards compatible?  Maybe just this one 
specifically?  USB 2.0 devices like mice are not recognized when 
attached.  A USB 3.0 memory stick is recognized.


The attached Ethernet port is still not seen.  Should rue(4) support the 
RTL8153?
