the lack of usb nic is because the xenial image does not have a "full
kernel" inside it .  14.04 maas images had linux-generic installed.  So
if you were commissioning with hwe-t (ie, you had no need for a newer
hwe kernel) then your commissioning would get all the drivers in linux-
generic at its disposal.

We can add drivers/net/usb to the boot-intird and we'd have more drivers
at the disposal.

Can you try using this attached 'boot-kernel' and 'boot-initrd' ?

To do that, on the maas server:
 kdir=/var/lib/maas/boot-resources/current/ubuntu/amd64/hwe-x/xenial/daily
 for x in boot-initrd boot-kernel; do
    [ -f "$kdir/$x.dist" ] || cp "$kdir/$x" "$kdir/$x.dist"
 done
 tar -C $kdir -xf test-kernel.txz

then restart maas cluster controller and try commission again.


For reference, the diff that produced this in maas-images was just:

Title:
  Xenial doesn't see all cores nor usb network dongle

Status in maas-images:
  Triaged
Status in linux package in Ubuntu:
  Confirmed

Bug description:
  When commissioning intel NUC's with MAAS 1.10 and the 16.04 Xenial image, the 
systems report in with only 1 core, on a 4 core system, and the secondary 
network interface (usb dongle), doesn't appear at all.
  Note: When loading 16.04 desktop onto node0 (control node), all the cores are 
seen and both secondary and tertiary usb network dongles are seen by the system.
