不编译内核，让usb serial识别新的上网卡

环境

linux3.10 高新兴物联ME3630-W pid:c3c 内核中已经有了usb serial的驱动

命令

echo '0x19d2 0x1476' > /sys/bus/usb-serial/drivers/option1/new_id

如下所示，就不需要去修改内核中的static const struct usb_device_id option_ids[]结构体了

# echo '0x19d2 0x1476' > /sys/bus/usb-serial/drivers/option1/new_id [ 87.036901] option 3-1:1.0: GSM modem (1-port) converter detected [ 87.045534] usb 3-1: GSM modem (1-port) converter now attached to ttyUSB0 [ 87.053459] option 3-1:1.1: GSM modem (1-port) converter detected [ 87.061535] usb 3-1: GSM modem (1-port) converter now attached to ttyUSB1 [ 87.069580] option 3-1:1.2: GSM modem (1-port) converter detected [ 87.077486] usb 3-1: GSM modem (1-port) converter now attached to ttyUSB2
