Basic Information: I have a flsun v400 device and its card burned out recently. I also have a BTT Manta M8P v2 card. I installed it in my device, but I couldn’t install the MCU card with the speederpad. The speederpad has a clipper installed. I just want to connect it to the card and check it. I use the USB port on the speederpad. I connect the other end of the cable to the Type-C card. pi@speeder-pad:~$ ls /dev/serial/by-id/  
usb-1a86\_USB\_Serial-if00-port0  
It comes up like this, but it doesn’t work. How can I do this? Please help.

Btw: [Creality Sonic Pad and Alternatives](https://klipper.discourse.group/t/creality-sonic-pad-and-alternatives/6324)

Generally, if you don’t know how to install a clean system and Klipper on your pad, I’m not sure it is usable or that we can help you with it.

That only means there is a USB2UART chip in between. I’m not sure where or what this means.

Generally, on old boards, there is no real USB 2 MCU connection.  
Instead, there is CH341 USB2SERIAL converter.  
So, if you try to connect to this type of motherboard, under the hood, it would connect like  
Klippy host → USB → CH341 → UART → MCU.  
Where on normal motherboards, it is:  
Klippy host → USB → MCU.  
Or  
Klippy host → UART → MCU.

The following overview shows how the different aspects interact. Only the red boxes is Klipper in its original sense, the other boxes are independent products forming the entire ecosystem.

So, to flash that motherboard, the SD card is used, and mcu should be configured for UART connection.

Hope that explains something.
