 Hello, Freebsd-usb.
 
   I've  implemented  driver (ucom-subdriver) for MosChip 7820 and 7840
  USB2COM multiport bridges. I have two questions:
 

Hi,

   (1)  How  should  I  specify  module-load  function? DRIVER_MODULE()
   doesn't   help   much.  I  need  to run some code only once, at very
   beginning,  not  for each probe/attach. GEOM modules have methods for
   it, but I can not find such methods for drivers.

Look at ubt_modevent in sys/netgraph/bluetooth/drivers/ubt/ng_ubt.c. Or use a 
so-called SYSINIT() or SYSUNINIT().

 
   (2) Which name should I choose? Working name of module/driver/device
   is mos7840, but it seems, that it is bad name:
(a) All existing ucom-based drivers is uXXXcom
(b) Driver instances looks ugly (like mos78400)
umos78400 ?

 
   Is  umos7840com  good name or it is too long? :) We have umoscom
   driver for older MosChip chip in base already.

Maybe someone else has some comments.

 Are you sure?
 The last two arguments to DRIVER_MODULE() look like what you want.
  Yes, it my fault, it works after hint from Hans Petter Selasky.

 Is it possible/sane to integrate two drivers in one?
  No, they are almost totally different.
