Unable to write bootloader to XIAO when in DFU

Hi All,

So received the Seeeduino XIAO, and wanted to install CircuitPython.
Powered my board, Double-RESET, WIndows 10 shows “Arduino” USB Drive. All looks good for launch.

Well, I cannot write the uf2 file to the above drive, nor any file, and also cannot read the .HTML or UF2.TXT file nor copy them off the XIAO.

My guess is a Windows issue, but figured I would reach out here.


AHA, cannot use USB2.0 with a Type C cable to connect XIAO to PC, must be USB3.0 with Type C cable.

Correctly connected and all is well.
