Now I run Zadig and replace the driver with WinUSB.

In this state, you can see in the Device Manager that there's an 'STM Device in DFU Mode.'

Be aware that you can mess up your system if you select something like your WebCam instead of the hardware device you mean to select. In my case the device was listened under STM32 Bootloader. Here you can see me finding the ST device within Zadig and replacing the driver with WinUSB. Run Zadig and click Options | List All Devices. Install a generic USB driver for your device - WinUSB using Zadig The issue is that the default 'inbox' driver that Windows uses for devices like this isn't set up for Generic USB access with libraries like 'libusb.' If you follow the instructions when flashing a device and don't have the right USB driver installed you'll likely get an error like this: Cannot open DFU device 0483:df11 you want to access a device using WinUSB.you want to upgrade a generic USB driver.you want to access a device using a libusb-based application.It can be especially useful for cases where: Such as WinUSB, libusb-win32/libusb0.sys or libusbK, to help you access USB devices. Zadig is a Windows application that installs generic USB drivers, Today, the easiest way to swap the 'inbox' driver with WinUSB is using a utility called Zadig. I, however, as an aristocrat, sometimes want to do low-level stuff and flash an OS on a Microcontroller. If you plug in a device, the vast majority of Windows users want the device to 'just work.' My non-technical parent doesn't want Generic USB drivers so they can flash the firmware on their mouse. The Mac and Linux instructions usually say something like 'plug it in and party on' but folks like myself with Windows have to set up a WinUSB Driver (libusb-win32 or libusbK) as dfu-util uses those libraries to speak to USB devices. Very often I'll find myself with a device like a Particle Photon, Wilderness Labs Meadow, or some STM32 device that uses the ST Bootloader. The term 'dfu' means Device Firmware Update and dfu-util is the Device Firmware Update Utility, natch. It can do most anything I want, run a half-dozen Linuxes, and has a shiny new open source Terminal, and has great support for Docker now.įor years - YEARS I SAY - Windows has been a huge hassle when you want to flash the firmware of various devices over USB. I'm pretty happy with Windows 10 as my primary development box.
