Libusb-win32 Others Driver Download Windows 10

I'm pretty happy with Windows 10 as my primary development box. 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.

However.

For years - YEARS I SAY - Windows has been a huge hassle when you want to flash the firmware of various devices over USB.

The term 'dfu' means Device Firmware Update and dfu-util is the Device Firmware Update Utility, natch.

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 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.

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. I, however, as an aristocrat, sometimes want to do low-level stuff and flash an OS on a Microcontroller.

Today, the easiest way to swap the 'inbox' driver with WinUSB is using a utility called Zadig. Per their docs:

Zadig is a Windows application that installs generic USB drivers,
such as WinUSB, libusb-win32/libusb0.sys or libusbK, to help you access USB devices.

It can be especially useful for cases where:

you want to access a device using a libusb-based application
you want to upgrade a generic USB driver
you want to access a device using WinUSB

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:

That's not a lot to go on. 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.'

Install a generic USB driver for your device - WinUSB using Zadig

Run Zadig and click Options | List All Devices.

Here you can see me finding the ST device within Zadig and replacing the driver with WinUSB. In my case the device was listened under STM32 Bootloader. 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 this state, you can see in the Device Manager that there's an 'STM Device in DFU Mode.'

Now I run Zadig and replace the driver with WinUSB. Here's the result. Note the SUCCESS and the changed Driver on the left.

Here the STM32 Bootloader device now exists in Universal Serial Bus Devices in Device Manager.

Now I can run dfu-util --list again. Note the before and after in the screenshot below. I run dfu-util --list and it finds nothing. I replace the bootloader with the generic WinUSB driver and run dfu-util again and it finds the devices.

At this point I can follow along and flash my devices per whatever instructions my manufacturer/project/boardmaker intends.

NOTE: When using dfu-util on Windows, I recommend you either be smart about your PATH and add dfu-util, or better yet, make sure the dfu-util.exe and libusb.dlls are local to your firmware so there's no confusion about what libraries are being used.

I'd love to see this extra step in Windows removed, but for now, I hope this write up makes it clearer and helps the lone Googler who finds this post.

Windows comes with drivers for many devices, such as printers, displays, keyboards, and TVs. A driver is software that a device uses to work with your PC. Every device needs a driver to work with your PC. So, in many cases, you can plug in a device, and it’ll work automatically.

Windows can also download device software and info. This might include an app that the device manufacturer created to go with your device or info like the product name, manufacturer, and model number, to help you distinguish between similar devices.

Drivers are updated occasionally. Windows can update them automatically, or you can install the updated drivers yourself. It's important for you to have confidence in the updated drivers you install. Windows notifies you if it detects a suspicious or unsafe driver you shouldn't install.

Automatically get the latest drivers and software

Windows Update checks for updated drivers and software for your devices and install them automatically. Keeping Windows Update on is a good way to make sure your devices continues to work properly and you get the best experience with them.

Note: PCs running Windows RT 8.1 always automatically download and install drivers, apps, and info for your devices.

To check that automatic updating is on

Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings. (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, click Settings, and then click Change PC settings.)
Tap or click Update and recovery, and then tap or click Windows Update.
Tap or click Choose how updates get installed.
Under Important updates, choose Install updates automatically (recommended).

Installing drivers yourself

If your device came with a disc, it might contain software that installs a driver. Before you install a driver from a disc, check the info that comes with it to be sure it supports your current version of Windows.

You can also search for new drivers on the manufacturer's website. Driver updates are often available in the support section of their website. Download the latest driver for your device, and follow the installation instructions on the website. You can usually double-tap or double-click the downloaded file to install the driver on your PC.

If the driver you got from a disc or downloaded from a website doesn't install itself, you might need to install manually.

To manually install a driver

You must be signed in as an administrator to follow these steps.

Swipe in from the right edge of the screen, and then tap Search. (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, and then click Search.)
Enter Device Manager in the search box, and tap or click Device Manager.
In the list of hardware categories, double-tap or double-click the category your device is in and then double-tap or double-click the device you want. For example, to see your video card, tap or click Display adapters, and then double-tap or double-click the video card name.
Tap or click the Driver tab, tap or click Update Driver, and then follow the instructions. You might be asked for an admin password or to confirm your choice.

Notifications telling you about unsafe drivers

Occasionally, you might see a notification that a driver is unsigned, has been changed since it was signed, or can't be installed by Windows. We recommend that you don't install unsigned or changed drivers.

A digitally signed driver includes a digital signature, which is an electronic security mark that indicates the publisher of software and whether someone has tampered with it since it was signed. If a driver has been signed by a publisher that has verified its identity with a certification authority, you can be confident that the driver comes from that publisher and hasn't been changed.

If you see any of the following notifications when you're installing a driver, you should stop the installation and go to your device manufacturer's website to get a digitally signed driver for your device.

Windows can't verify the publisher of this driver software

The driver doesn't have a digital signature or has been signed with a digital signature that wasn't verified by a certification authority. You should only install this driver if you got it from the manufacturer's disc or from your system administrator.

This driver hasn't been signed

The driver hasn't been digitally signed by a verified publisher. The driver might have been changed to include malware that could harm your PC or steal info. In rare cases, legitimate publishers do change drivers after they've been digitally signed, but you should only install an unsigned driver if you got it from a device manufacturer's disc.

Unfortunately, there's no trustworthy source of info that indicates who has published an unsigned driver. Anyone can change the contents of an unsigned driver, and there's no way to know why it was changed. Most manufacturers now digitally sign the drivers they create before releasing them to the public.

Windows requires a digitally signed driver

A driver that lacks a valid digital signature, or has a signature that was changed after it was signed, can't be installed on 64-bit versions of Windows. You'll only see this notification if you have a 64-bit version of Windows and try to install such a driver on it.
