Atmel DFU Bootloader (Translated by Google)

This is the default bootloader for some AVR microcontrollers. It is also used directly by many keyboards.

To use this bootloader to clean the firmware, you must install the driver. Use zadig. To prevent the installation of the wrong device, you can use the modified version of Zadig for Atmel DFU.

1.After pressing the brush button, be sure to press , from the list below, find ATm32U4DFU . (This
One sentence is very important, you must find the ATm32U4DFU and then install the driver after pressing the brush button. Because it is very important, let's say it again. )

Once again, once prompted to press the button, as shown above, do not choose other displays. Anything shown is for a winusb driver. Don’t choose GH60 or other keyboard name, if If you choose this driver, the keyboard will not work. You need to uninstall the driver or plug in the USB interface.

After the correct selection of ATm32U4DFU, click Install Driver, the installation will be prompted.

As shown above, the Driver is displayed as WinUSB, indicating that the installation was successful. If the installation is not successful, Always, or try running zadig_2.1.2.exe as an administrator.

  Some WinSystem drivers may not be supported on a streamlined system, so you can also choose to install the LibUSB driver.   The brush tool provided by YDKB supports both libusb and winusb drivers.

If you have multiple keyboards, use the tkg brush, it is recommended to install the WinUSB driver, because the tkg brush firmware tool uses WinUSB. If you have a keyboard using qmk, it is recommended to install the LibUSB driver. The qmk brush firmware tool uses LibUSB.
