hi guys, i get some LTE module HUAWEI model EC200AEUHA-N06-SNASA , this 
module arent' recognized from the kernel, or better, the kernel 
recognize the CDC-ETHER section, but not the ttyUSB were i must 
configure the APN and lunch the connection

root at OpenWrt:~# lsusb
Bus 002 Device 001: ID 1d6b:0001 Linux 5.4.203 ohci_hcd Generic Platform

it's the 2c7c:6005 usbid

then i check for huawei support and they pointed me in the right 
direction (they give me the source code for some x64 processor)

i check it, and some other pdf and i try to patch openwrt

i downloaded the openwrt code, and tried to modify the option.c file under

openwrt/build_dir/target-mipsel_24kc_musl/linux-ramips_mt76x8/linux-5.4.203/drivers/usb/serial/option.c

adding the definition for this pid


#define QUECTEL_PRODUCT_RM500K                  0x7001
+#define QUECTEL_PRODUCT_EC200A                  0x6005
#define CMOTECH_VENDOR_ID                       0x16d8


         { USB_DEVICE_AND_INTERFACE_INFO(QUECTEL_VENDOR_ID, 
QUECTEL_PRODUCT_EC200S_CN, 0xff, 0, 0) },
+        { USB_DEVICE_AND_INTERFACE_INFO(QUECTEL_VENDOR_ID, 
QUECTEL_PRODUCT_EC200A, 0xff, 0, 0) },
         { USB_DEVICE_AND_INTERFACE_INFO(QUECTEL_VENDOR_ID, 
QUECTEL_PRODUCT_EC200T, 0xff, 0, 0) },


i complie the code and it's work, now i've the ttyUSB0 to 2 device
