Free Download Android Mobile USB Drivers For Windows. Click Here To Download the Android USB driver on Windows. By installing these drivers, you will be able to connect your mobile or tablet to your computer to transfer files on both sides, while dispensing with Kies software. If the USB drivers are not installed, the computer will not detect the device and when you connect it, it will be prompted to extract the drivers from the device. USB, short for Universal Serial Bus, is an industry standard developed in the mid-1990s that defines the cables, connectors and communications protocols used in a bus for connection, communication, and power supply between computers and electronic devices. It is currently developed by the USB Implementers Forum.

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.

The latest trial has successfully ended in September 2017.

Privacy and security #

HTTPS only #

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 #

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.

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.

I want more #

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

• 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.

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.

One of the easiest and most popular ways to connect any external device to your computer is through Universal Serial Bus Connector or known as USB in short. All device manufacturers provide a USB port to connect and laptop manufacturers provide more than a couple of USB ports. This brings us to today’s topic on how to update USB drivers in Windows 10, but this also raises the question that is it really important to update USB drivers?

The answer to that is simply provided you know what drivers do in your system. Drivers are small programs or codes that help establish a communication between the software and the hardware. In other words, if the USB drivers are not updated, then any device you connect to the USB ports will not be recognized or detected by your computer. If you are facing any issues with your USB devices not working, then here are few troubleshooting methods to resolve USB issues focusing on how to facilitate USB update on Windows 10.

Different Methods On How To Update USB Drivers In Windows 10?

There are four Basic Methods on how you can perform a USB update in Windows 10. I have described all methods thoroughly below:

Method 1: Manufacturer Website

The first method of updating drivers is to search, download and install them from the manufacturer’s website. All hardware manufacturers maintain a specific website where users can find drivers for their products. One of the greatest challenges in this method is the identification of the hardware make and model. If you cannot identify your hardware, then you should try a different method because installing mismatched drivers would not be beneficial.

In case of updating USB drivers in Windows 10, you would have to look for your motherboard or chipset drivers. The USB drivers would not be available separately as they form a part of the circuits on your mainboard in the CPU tower.

Method 2: Windows Update

Drivers Simple USB Devices

Moving on to the second method, you can use the Windows Updates feature to update your drivers. Microsoft provides regular patches to its Windows 10 users related to applications, security, drivers, etc. Most hardware manufacturers develop driver patches and send them to the Microsoft research team which then checks and analyzes the driver patch before releasing them to the Windows 10 users. However, the Windows Update for USB drivers is a slow process as these patches are downloaded from the Microsoft Server only.

Here are the steps to initiate Windows Update for USB drivers on your PC:

Step 1: Press Windows + I to launch the Settings window.

Step 2: Choose Update & Security and click on Windows Update in the left panel of the window.

Step 3: Now, click on Check for Updates button in the right panel and follow the onscreen instructions.

Step 4: Restart your computer after the update process is completed for the changes to take effect.

Note: If the manufacturer did not submit the latest update to the Microsoft Servers, then you will not be able to download it on your system through this method.

Method 3: Device Manager

The next method for USB update in Windows 10 is to use Microsoft’s inbuilt driver utility known as Device Manager. This tool maintains all the records of drivers installed in the system and displays a list categorized by hardware in your PC. Unlike Windows Updates, users can use the Device Manager to download drivers for one particular hardware only like USB drivers. Windows Updates consist of large files and downloads that include a lot of patches other than drivers. Here are the steps to use the Device Manager on Windows 10 PC:

Step 1: Press Windows + I on the keyboard and type devmgmt.msc in the text box followed by Enter.

Step 2: A new window will open displaying all the drivers installed in your system. Scroll down and locate Universal Serial Bus Controllers.

Step 3: Click USB to reveal the dropdown and then right-click each item to reveal the context menu and select the Update Driver option.

Step 4: Next, click on Search Automatically For Updated Driver Software, and Windows will automatically search and download the latest driver for you.

Method 4: Driver Updater Application

The final method to update drivers is by using a Driver Updater Application like Smart Driver Care. This application requires less time and effort with a 100% success rate as it is automated software. Smart Driver Care scans your PC and identifies all the driver issues with a few mouse clicks. Not only this, but it also searches its database and the internet for the latest updated drivers and installs them on your system. Here are the steps to use Smart Driver Care on your computer:

Step 1: Download and Install Smart Driver Care on your computer by clicking the link below.

Step 2: Once installed, open the application and click on the Start Scan button.

Step 3: Once the scanning process terminates, you will have a list of driver issues on your system. Click the Update driver link beside the USB Drivers in the list.

Step 4: Wait for the app to search, download and install the latest updated drivers on your PC.

Step 5: Restart your PC for the changes to take effect.
