No.

puc0 pnpinfo vendor=0x1409 device=0x7168 subvendor=0x1409 subdevice=0x4056 class=0x070002 at slot=10 function=0
  uart2
  uart3

(If you want the complete output of devinfo just ask - I assumed from
your question you only wanted the puc-releated section.)

BTW I saw the patch for puc(4) you just posted to current at .  Is it worth
me trying that?

Many thanks.


Cheers,
       Nick.
