If you are using the lsusb command and you still cannot see the 2C7C. Normally it is a hardware problem.
It need to check
- Whether the USB modem power on;
- Try another USB cable;
- Check the SCH and the PCB.
Hello Sir,
I am also interfacing the Quectel EC200U module by 7Semi with Luckfox Pico Mini B Linux Board. I have enabled USB generic serial driver in SDK and compiled it. Also I have set Luckfox Pico board USB C port to host mode and connected to ec200u module via USB. I am powering EC200U from external power supply. When I enter lsusb it shows usb device as 2C7C. But I need to know the further process for providing internet connectivity. Please help me.
Hi @Saurabh.A
Please follow the Quectel_UMTS_LTE_5G_Linux_USB_Driver_User_Guide_V3.3.pdf which you can find it in the downloadZone to modify the Linux kernel.
Can you see the /dev/ttyUSBx and the usb0 interface?
Please show
ls /sys/bus/usb/drivers/
Make sure we can see the /dev/ttyUSBx and usb0 first.
And then follow the AT command guide to send the AT command to enable the data.
AT+QNETDEVCTL=1,1,1
And then we can get the ip with dhcp client.
I am not able to see /dev/ttyUSBx or usb0 interface. Check image.
Just for sending AT command, you can try
echo 2C7C 0901 > /sys/bus/usb-serial/drivers/generic/new_id
then you can see the ttyUSB.
You should enable the option driver and cdc_ether driver.
