The model we bought is the EC200A-CN domestic version of Yuanyuan Communication, help to do the kernel configuration
You turn on these macro switches in the kernel
- usb to serial port function
CONFIG_USB_SERIAL
CONFIG_USB_SERIAL_WWAN
CONFIG_USB_SERIAL_OPTION
- usb card driver
CONFIG_USB_USBNET=y
CONFIG_USB_NET_CDCETHER=y
CONFIG_USB_NET_RNDIS_HOST=y
CONFIG_USB_NET_QMI_WWAN
CONFIG_USB_WDM
CONFIG_USB_NET_DRIVERS
CONFIG_USB_USBNET
- Supports the PPP dialing function
CONFIG_PPP
CONFIG_PPP_ASYNC
CONFIG_PPP_SYNC_TTY
CONFIG_PPP_DEFLATE
The kernel configuration did not add vid and pid. After turning on the above macro switch, the device can be recognized, but the module does not work, the module vid: 2c7c and pid: 6005
