The ASUS Keystone is a physical NFC-like dongle that slots into supported ASUS laptops. The EC fires WMI notify code 0xB4 on insert/remove events. Expose the current insert state via a sysfs attribute by querying WMI device ID 0x00120091 (DSTS). This devid does not follow the standard DSTS convention: PRESENCE_BIT (0x00010000) encodes the insert state rather than feature presence, and STATUS_BIT is never set. Presence of a keystone slot is detected by a successful DSTS call.
