1. 準備編譯環境

1.1 下載linux內核，準備編譯環境，請參看“RaspberryPi4B 樹莓派4B Linux5.4.y 內核編譯”

1.2 修改usb串口驅動， drivers/usb/serial/option.c

static const struct usb_device_id option_ids[] = { #if 1 //Added by Quectel{ USB_DEVICE(QUALCOMM_VENDOR_ID, 0x9215) }, /* Quectel EC20 */{ USB_DEVICE(QUECTEL_VENDOR_ID, 0x6026) }, /* Quectel EC200 */{ USB_DEVICE(QUECTEL_VENDOR_ID, 0x6120) }, /* Quectel UC200 */{ USB_DEVICE(QUECTEL_VENDOR_ID, 0x6000) }, /* Quectel EC200/UC200 */ #endif

1.3 增加休眠后喚醒接口

static struct usb_serial_driver option_1port_device = {.driver = {.owner = THIS_MODULE,.name = "option1",},.description = "GSM modem (1-port)",...#ifdef CONFIG_PM.suspend = usb_wwan_suspend,.resume = usb_wwan_resume, #if 1 //add by Quecte
