It's "Communications Device Class", a composite device like a modem.
It's sort of a one-size-fits-all name for a grouping of functions that
by themselves may be generic(but not neccessarily) but as a group are
nonstandard.

If you search for "USB CDC" it should point you to the spec and other
documents.

The FTDI chips can run either as virtual com ports or as CDC's so you
can reach the extra registers(and do more bitrates).

Cheerful regards,

Bob
