Bjørn Mork423ce8c2012-01-19 15:37:22 +000024 * specific management protocol called Qualcomm MSM Interface (QMI) -
25 * in addition to the more common AT commands over serial interface
26 * management
27 *
28 * QMI is wrapped in CDC, using CDC encapsulated commands on the
29 * control ("master") interface of a two-interface CDC Union
30 * resembling standard CDC ECM. The devices do not use the control
31 * interface for any other CDC messages. Most likely because the
32 * management protocol is used in place of the standard CDC
33 * notifications NOTIFY_NETWORK_CONNECTION and NOTIFY_SPEED_CHANGE
34 *
Bjørn Mork230718b2012-06-19 00:42:01 +000035 * Alternatively, control and data functions can be combined in a
36 * single USB interface.
37 *
Bjørn Mork423ce8c2012-01-19 15:37:22 +000038 * Handling a protocol like QMI is out of the scope for any driver.
Bjørn Mork230718b2012-06-19 00:42:01 +000039 * It is exported as a character device using the cdc-wdm driver as
40 * a subdriver, enabling userspace applications ("modem managers") to
41 * handle it.
Bjørn Mork423ce8c2012-01-19 15:37:22 +000042 *
43 * These devices may alternatively/additionally be configured using AT
Bjørn Mork230718b2012-06-19 00:42:01 +000044 * commands on a serial interface
