Hi USB serial experts, I am trying to support ZTE 403ZT modem by linux serial driver. Currently, option driver can not be used for the modem, because USB Class Code of the modem does not match. Linux driver has 0xff as USB Class Code for the modem but the device actually has 0x00. By default, option driver has this device ID with the following configuration: { USB_DEVICE_AND_INTERFACE_INFO(ZTE_VENDOR_ID, 0x1282, 0xff, 0xff, 0xff) }, I have changed the configuration as follows, and it works fine. { USB_DEVICE(ZTE_VENDOR_ID, 0x1282) }, Is this a genuine bug? Or is there any other way to use the option driver for the modem?
