We have not encountered this problem in win10 computers, so we have not prepared drivers for xiao. Under normal circumstances, Windows 10 will automatically complete the driver installation. My suggestion is to use software to check whether the computer’s driver is missing, and install zagdig.
I found that Windows after upgrading to version 21H2 cannot recognize that I connected the Seeduino XIAO microcontroller (ATSAMD21G18A) to the USB port and therefore the system reports an error that the device manufacturer (VID_03EB = Atmel Corp.) and its device (PID_2403 = THE MICRO, ATSAMD21G18A) was not recognized. The device worked fine before the upgrade.
The problem was caused by a sketch that put XIAO to sleep and turn off the GLCK peripheral clock at the same time. At the specified time, XIAO woke up, but the print to the serial monitor and USB port did not work.
The seeedstudio support advised me to activate bootloader mode, which restarted the GLCK clock and made it possible to upload the sketch.
