 Put your keyboard into bootloader mode, either by hitting the `RESET` keycode (which may be on a different layer), or by pressing the reset switch that's usually located on the underside of the board. If your keyboard has neither, try holding Escape or Space+`B` as you plug it in (see the [Bootmagic](feature_bootmagic.md) docs for more details). Some boards use [Command](feature_command.md) instead of Bootmagic; in this case, you can enter bootloader mode by hitting Left Shift+Right Shift+`B` or Left Shift+Right Shift+Escape at any point while the keyboard is plugged in.
 Some keyboards may have specific instructions for entering the bootloader. For example, the [Bootmagic Lite](feature_bootmagic.md#bootmagic-lite) key (default: Escape) might be on a different key, e.g. Left Control; or the magic combination for Command (default: Left Shift+Right Shift) might require you to hold something else, e.g. Left Control+Right Control. Refer to the board's README file if you are unsure.
 
+To put a device in bootloader mode with USBaspLoader, tap the `RESET` button while holding down the `BOOT` button.
+Alternatively, hold `BOOT` while inserting the USB cable.

 Zadig will automatically detect the bootloader device. You may sometimes need to check **Options → List All Devices**.

  - For keyboards with Atmel AVR MCUs, the bootloader will be named something similar to `ATm32U4DFU`, and have a Vendor ID of `03EB`.
  - USBasp bootloaders will appear as `USBasp`, with a VID/PID of `16C0:05DC`.
  - AVR keyboards flashed with the QMK-DFU bootloader will be named `<keyboard name> Bootloader` and will also have the VID `03EB`.

 !> If Zadig lists one or more devices with the `HidUsb` driver, your keyboard is probably not in bootloader mode. The arrow will be colored orange and you will be asked to confirm modifying a system driver. **Do not** proceed if this is the case!
 
-If the arrow appears green, select the driver, and click **Install Driver**. The `libusb-win32` driver will usually work for AVR, and `WinUSB` for ARM, but if you still cannot flash the board, try installing a different driver from the list.

The `libusb-win32` driver will usually work for AVR, and `WinUSB` for ARM, but if you still cannot flash the board, try installing a different driver from the list. For flashing a USBaspLoader device via command line with msys2, the `libusbk` driver is recommended, otherwise `libusb-win32` will work fine if you are using QMK Toolbox for flashing.
