7、了 5个usb接口，接口 0-3需要适配usbserial驱动，通过 ttyUSB2节点使用PPP拨号上网；接口 4需要适配GobiNetorQMIWWAN 驱动， 使用quectel-CM应用上网。三、USB Serial驱动移植usb 串口驱动有两种适配方式，修改(KERNEL/drivers/usb/serial/)option.c 或 qcserial.c 文件。option.c： USBDriverforGSMmodemsqcserial.c： QualcommSerialUSBdriveroption驱动. TX2板子使用的kernel已经支持option.c文件产生的USBSer

8、ialDriver ；.对于不支持的kernel，按照如下方式修改。修改KERNEL/drivers/usb/serial/option.c 支持 EC20R2.0(1)添加VID和PIDstatic const struct usb_device_id option_ids = USB_DEVICE(0 x2C7C, 0 x0125),/* Quectel EC25/EC20 R2.0 */(2)下面2个文件，需要删除usb_device_id数组中VID和PID的元素，内核没有 编译该文件或不加载qcserial.ko/qmi_wwan.ko的话，可以不用修改。KERNEL/drivers

9、/usb/serial/qcserial.cKERNEL/drivers/net/usb/qmi_wwan.c qmi_wwan.c驱动和option.c驱动使用不同的usb接口，应该是不冲突的，但是参 考手册说因为冲突需要删除。(3)AddtheZeroPacketMechanism(4)AddResetResume(掉电恢复)备注：（3） （4）两项TX2 kernel源码中没有修改，应该对于4G上网功能影响不大， 算是辅助功能，这里没有深入分析。.测试（1）力口载option.ko并插上4G模块，dmesg信息如下usbco re: regietered neu interface dr
