 - Extensible with CTAP apps: currently FIDO and Admin are active;
-- Does not work with Firefox at the moment;
+- Does not work with Firefox' CTAP1 at the moment;
 - Allows to inject own FIDO certificates, and device properties;
+- Mostly stable CCID support (WIP);
 - Requires multiple `usbip attach` calls to make it work [1].
