The OTG core will use struct otg_hcd_ops to interface
with the HCD controller.

   Host controller driver (HCD) controller? Maybe just HC? :-)

OK.

   OTOH, my googling has shown that HCD may stand for both HC driver and HC device... The host controller device sounds a bit tautological however...

Yeah I always meant it to be Host Controller Device :).

    The question here is more what was meant by the previous Linux USB 
authors. :-)

I have always used "HCD" to mean Host Controller Driver, and I believe 
that's what other people have done too.

If I want to refer to a Host Controller Device, I would write either
"HC" or "host controller".

Admittedly, this means that struct usb_hcd has a slightly illogical 
name.
