I'm not aware of any drivers for the CE6230 (in fact, this is the
first device I've heard of that uses it so far). Someone will have to
try and get the docs from Intel - I don't think these are exactly
simple devices. (They have a full programmable 8051 microprocessor
core on-chip in addition to stuff like a seperate hardware PID filter
and a fairly intelligent demodulator. OTOH, the demodulator is
probably based on one of the Zarlink designs, which makes life
slightly easier).

Yep - it's an integrated USB interface and demodulator on a chip. They
seem to be becoming more common these days, possibly due to potential
cost savings. Probably has more in common with the ZL10353/CE6353 and
company - the MT352/MT353 had been throughly obsoleted by them by the
time Intel bought out Zarlink, to the point that Intel didn't even
bother giving them new Intel part numbers.
