Actually I suspect that George has an HSF modem (which is incorrectly labeled
as HCF in some old PCI ID lists as described above). Our HSF driver does
work with some 127A: HSF devices.

The old 127A:1xxx HCF chips (except those on riptide cards) need a bunch of
special workarounds as well as different code for the data pump.

Historically, the windows driver started off supporting them, but
our linux HCF driver has a completely different (newer) architecture
that focuses on the more recent chips. Implementing support for the old
chips in the new driver would require a lot of time and effort, an investment
which is hard to justify for obsolete products.
