Before you begin

If drivers were not downloaded automatically by Windows Update, use Device Manager to refresh the driver from Windows Update, or contact the device manufacturer I’m Moli, your virtual agent. I can help with Moto phone issues. The Audio Device Class Definition applies to all devices or functions embedded in composite devices that are used to manipulate audio, voice, and sound-related functionality. This includes both audio data (analog and digital) and the functionality that is used to directly control the audio environment, such as Volume and Tone Control. If a USB storage device is already installed on the computer. If a USB storage device is already installed on the computer, you can change the registry to make sure that the device does not work when the user connects to the computer. ResolutionImportant This section, method, or task contains steps that tell you how to modify the registry.

Driver updates for Windows 10, along with many devices, such as network adapters, monitors, printers, and video cards, are automatically downloaded and installed through Windows Update. You probably already have the most recent drivers, but if you'd like to manually update or reinstall a driver, here's how:

Update the device driver

  1. In the search box on the taskbar, enter device manager, then select Device Manager.

  2. Select a category to see names of devices, then right-click (or press and hold) the one you’d like to update.

  3. Select Search automatically for updated driver software.

  4. Select Update Driver.

  5. If Windows doesn't find a new driver, you can try looking for one on the device manufacturer's website and follow their instructions.

Reinstall the device driver

  1. In the search box on the taskbar, enter device manager, then select Device Manager.

  2. Right-click (or press and hold) the name of the device, and select Uninstall.

  3. Restart your PC.

  4. Windows will attempt to reinstall the driver.

Access USB Devices on the Web

If I said plainly and simply 'USB', there is a good chance that you will immediately think of keyboards, mice, audio, video, and storage devices. You're right but you'll find other kinds of Universal Serial Bus (USB) devices out there.

These non-standardized USB devices require hardware vendors to write native drivers and SDKs in order for you (the developer) to take advantage of them. Sadly this native code has historically prevented these devices from being used by the Web. And that's one of the reasons the WebUSB API has been created: to provide a way to expose USB device services to the Web. With this API, hardware manufacturers will be able to build cross-platform JavaScript SDKs for their devices. But most importantly this will make USB safer and easier to use by bringing it to the Web.

Let's see the behavior you could expect with the WebUSB API:

  1. Buy a USB device.
  2. Plug it into your computer. A notification appears right away, with the right website to go to for this device.
  3. Click the notification. The website is there and ready to use!
  4. Click to connect and a USB device chooser shows up in Chrome where you can pick your device.

Tada!

What would this procedure be like without the WebUSB API?

  1. Install a platform-specific application.
  2. If it's even supported on my operating system, verify that I've downloaded the right thing.
  3. Install the thing. If you're lucky, you'll get no scary OS prompts or popups warning you about installing drivers/applications from the internet. If you're unlucky, the installed drivers or applications malfunction and harm your computer. (Remember, the web is built to contain malfunctioning websites).
  4. If you only use the feature once, the code stays on your computer until you think to remove it. (On the Web, the space for unused is eventually reclaimed.)

Before I start #

This article assumes you have some basic knowledge of how USB works. If not, I recommend reading USB in a NutShell. For background information about USB, check out the official USB specifications.

The WebUSB API is available in Chrome 61.

Available for origin trials #

In order to get as much feedback as possible from developers using the WebUSB API in the field, we've previously added this feature in Chrome 54 and Chrome 57 as an origin trial.

Drivers Y-e Data USB Devices

The latest trial has successfully ended in September 2017.

Privacy and security #

HTTPS only #

Drivers Y-e Data Usb Devices Usb

Because of this feature's power, it only works on secure contexts. This means you'll need to build with TLS in mind.

User gesture required #

As a security precaution, navigator.usb.requestDevice() may only be called through a user gesture such as a touch or mouse click.

Feature Policy #

A feature policy is a mechanism that allows developers to selectively enable and disable various browser features and APIs. It can be defined via an HTTP header and/or an iframe 'allow' attribute.

You can define a feature policy that controls whether the usb attribute is exposed on the Navigator object, or in other words if you allow WebUSB.

Below is an example of a header policy where WebUSB is not allowed:

Below is another example of a container policy where USB is allowed:

Let's start coding #

The WebUSB API relies heavily on JavaScript Promises. If you're not familiar with them, check out this great Promises tutorial. One more thing, () => {} are simply ECMAScript 2015 Arrow functions.

Get access to USB devices #

Drivers Y-e Data Usb Devices Windows 10

You can either prompt the user to select a single connected USB device using navigator.usb.requestDevice() or call navigator.usb.getDevices() to get a list of all connected USB devices the origin has access to.

The navigator.usb.requestDevice() function takes a mandatory JavaScript object that defines filters. These filters are used to match any USB device with the given vendor (vendorId) and, optionally, product (productId) identifiers. The classCode, protocolCode, serialNumber, and subclassCode keys can also be defined there as well.

For instance, here's how to get access to a connected Arduino device configured to allow the origin.

Before you ask, I didn't magically come up with this 0x2341 hexadecimal number. I simply searched for the word 'Arduino' in this List of USB ID's.

The USB device returned in the fulfilled promise above has some basic, yet important information about the device such as the supported USB version, maximum packet size, vendor, and product IDs, the number of possible configurations the device can have. Basically it contains all fields in the device USB Descriptor.

By the way, if a USB device announces its support for WebUSB, as well as defining a landing page URL, Chrome will show a persistent notification when the USB device is plugged in. Clicking this notification will open the landing page.

From there, you can simply call navigator.usb.getDevices() and access your Arduino device as shown below.

Talk to an Arduino USB board #

Okay, now let's see how easy it is to communicate from a WebUSB compatible Arduino board over the USB port. Check out instructions at https://github.com/webusb/arduino to WebUSB-enable your sketches.

Don't worry, I'll cover all the WebUSB device methods mentioned below later in this article.

Please keep in mind that the WebUSB library I'm using here is just implementing one example protocol (based on the standard USB serial protocol) and that manufacturers can create any set and types of endpoints they wish. Control transfers are especially nice for small configuration commands as they get bus priority and have a well defined structure.

And here's the sketch that has been uploaded to the Arduino board.

The third-party WebUSB Arduino library used in the sample code above does basically two things:

  • The device acts as a WebUSB device enabling Chrome to read the landing page URL.
  • It exposes a WebUSB Serial API that you may use to override the default one.

Look at the JavaScript code again. Once I get the device picked by the user, device.open() runs all platform-specific steps to start a session with the USB device. Then, I have to select an available USB Configuration with device.selectConfiguration(). Remember that a configuration specifies how the device is powered, its maximum power consumption and its number of interfaces. Speaking of interfaces, I also need to request exclusive access with device.claimInterface() since data can only be transferred to an interface or associated endpoints when the interface is claimed. Finally calling device.controlTransferOut() is needed to set up the Arduino device with the appropriate commands to communicate through the WebUSB Serial API.

Drivers Y-e Data USB Devices

From there, device.transferIn() performs a bulk transfer onto the device to inform it that the host is ready to receive bulk data. Then, the promise is fulfilled with a result object containing a DataViewdata that has to be parsed appropriately.

If you're familiar with USB, all of this should look pretty familiar.

The WebUSB API lets you interact with the all USB transfer/endpoint types:

Drivers y-e data usb devices windows 10
  • CONTROL transfers, used to send or receive configuration or command parameters to a USB device, are handled with controlTransferIn(setup, length) and controlTransferOut(setup, data).
  • INTERRUPT transfers, used for a small amount of time sensitive data, are handled with the same methods as BULK transfers with transferIn(endpointNumber, length) and transferOut(endpointNumber, data).
  • ISOCHRONOUS transfers, used for streams of data like video and sound, are handled with isochronousTransferIn(endpointNumber, packetLengths) and isochronousTransferOut(endpointNumber, data, packetLengths).
  • BULK transfers, used to transfer a large amount of non-time-sensitive data in a reliable way, are handled with transferIn(endpointNumber, length) and transferOut(endpointNumber, data).

You may also want to have a look at Mike Tsao's WebLight project which provides a ground-up example of building a USB-controlled LED device designed for the WebUSB API (not using an Arduino here). You'll find hardware, software, and firmware.

Tips #

Debugging USB in Chrome is easier with the internal page chrome://device-log where you can see all USB device related events in one single place.

The internal page chrome://usb-internals also comes in handy and allows you to simulate connection and disconnection of virtual WebUSB devices. This is be useful for doing UI testing without for real hardware.

On most Linux systems, USB devices are mapped with read-only permissions by default. To allow Chrome to open a USB device, you will need to add a new udev rule. Create a file at /etc/udev/rules.d/50-yourdevicename.rules with the following content:

where [yourdevicevendor] is 2341 if your device is an Arduino for instance. ATTR{idProduct} can also be added for a more specific rule. Make sure your user is a member of the plugdev group. Then, just reconnect your device.

Camera

Microsoft OS 2.0 Descriptors used by the Arduino examples only work on Windows 8.1 and later. Without that Windows support still requires manual installation of an INF file.
