Unable to connect through usb

Hello,

I tried to connect my VIM3 board to my computer through USB C in order to flash it.
I set the udev rules

# khadas vim3 initial flashing
# idVendor=1b8e, idProduct=c003
SUBSYSTEM=="usb", ATTR{idVendor}=="1b8e", ATTR{idProduct}=="c003", MODE="0660", GROUP="plugdev"

# khadas vim3 fastboot (initial bootloader)
# idVendor=1b8e, idProduct=fada,
SUBSYSTEM=="usb", ATTR{idVendor}=="1b8e", ATTR{idProduct}=="fada", MODE="0660", GROUP="plugdev"


SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4e04", MODE="0666", GROUP="plugdev"
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", MODE="0666", GROUP="plugdev" 

and here is the message error in dmesg

If I do a lsusb I could not find the board

does someone has an idea to help me to flash the unit ?

Thanks
