回复: [PATCH] USB: serial: option: add Quectel EM060K modem

[谭 永林]

Dear Johan,

The last interface is used for Qualcomm WWAN module's QDSS(Qualcomm Debug Sub-System) port. Users use the QDSS interface to acquire Modem subsystem log. It is used to work with DIAG port. Therefore, we don't have to bind this interface with any driver.
