Driver for windows

Zadig image

Zadig is the recommended tool to install drivers in Windows. The bootloader (4348,55E0) should be installed with WinUSB or libusb-win32 driver.

You can use USB Serial (CDC) driver for default CDC USB stack. If you tried to emulate another type of USB device without changing the PID/VID, you may need to uninstall the device before installing a new driver.
