what else is it?

It's a fingerprint device/biometrics that should be handled by the
Goodix MOC driver in libfprint. libfprint supports some Goodix devices
but not all. I _suspect_ that other PID's from the same VID and
class/subclass/protocol will also match the ACM driver.

The CDC ACM driver is false matching the Goodix Fingerprint device against
the USB_CDC_ACM_PROTO_AT_V25TER.

Hi,

what else is it? Which driver should be used or is it to be handled
in user space? That needs to go into the change log. Otherwise
this patch just looks like it drops every access to the device.
