The package provides the installation files for Microsoft WinUSB Device Driver version 1.0.0.0. In order to manually update your driver, follow the steps below (the next steps): 1. Go to Device Manager (right click on My Computer, choose Manage and then find Device Manager in the left panel) 2.
The WinUSB architecture consists of a kernel-mode driver (Winusb.sys) and a user-mode dynamic link library (Winusb.dll). Note WinUSB driver packages that are built by using Windows Driver Kit for Windows 7 can automatically redistribute and install version 1.9 of the files. During driver package installation, the package checks the computer to. A Linux program to create Windows USB stick installer from a real Windows DVD or an image. This package contains two programs: WinUSB-gui: a simple tool that enable you to create your own usb stick windows installer from iso image or a real DVD. Winusb: the command line tool. Supported images: Windows Vista, Windows 7, Window 8.
This section describes the generic WinUSB driver (Winusb.sys) and its user-mode component (Winusb.dll) provided by Microsoft for all USB devices.
In versions of Windows earlier than Windows XP with Service Pack 2 (SP2), all USB device drivers were required to operate in kernel mode. If you created a USB device for which the operating system did not have a native class driver, you had to write a kernel-mode device driver for your device.
Windows USB (WinUSB) is a generic driver for USB devices that was developed concurrently with the Windows Driver Frameworks (WDF) for Windows XP with SP2. The WinUSB architecture consists of a kernel-mode driver (Winusb.sys) and a user-mode dynamic link library (Winusb.dll) that exposes WinUSB functions. By using these functions, you can manage USB devices with user-mode software.
Winusb.sys is also a key part of the link between a UMDF function driver and the associated device. Winusb.sys is installed in the device's kernel-mode stack as an upper filter driver. An application communicates with the device's UMDF function driver to issue read, write, or device I/O control requests. The driver interacts with the framework, which passes the request to Winusb.sys. Winusb.sys then processes the request and passes it to the protocol drivers and ultimately to the device. Any response returns by the reverse path. Winusb.sys also serves as the device stack's Plug and Play and power owner.
Note WinUSB functions require Windows XP or later. You can use these functions in your C/C++ application to communicate with your USB device. Microsoft does not provide a managed API for WinUSB.
This section describes how to use WinUSB to communicate with your USB devices. The topics in this section provide guidelines about choosing the correct driver for your device, information about installing Winusb.sys as a USB device's function driver, and a detailed walkthrough with code examples that show how applications and USB devices communicate with each other.

USB port types and names
USB (Universal Serial Bus) is an industry standard for connecting computers and other devices. It's available with many types of ports, and each type has a unique shape. On Mac computers, USB is available with these ports, depending on your Mac model:
USB-A
Type USB-A ports are commonly called USB, USB 2, or USB 3 ports, depending on the USB specification they support. They aren't reversible, so a USB-A connector plugs into the port only when oriented correctly.
USB-C
Type USB-C ports are available as either standard USB-C ports or Thunderbolt 3 ports that also support USB-C connections. They both look the same, and the connector plugs into the port in either orientation.

USB specifications
USB specifications are important primarily when you want the most speed and power for your USB device, or your device needs more power or is using too much power. Every USB port supports a particular USB specification, which determines the port's maximum>USB specifications on MacData transferPowerUSB 3.1 Gen 2

To learn which specification is supported by a type USB-A or type USB-C port on your Mac model:
- Choose Apple menu > About This Mac, click Support, then click Specifications.
- Check the System Information app for more details, including about USB devices connected to USB ports on your Mac. Select USB in the sidebar, then select a USB bus on the right.

Get the best performance from your USB devices
Winusb For Mac
USB specifications all work with each other, but speed and power are limited by the cable or device that uses the earliest specification. For example, if you connect a USB 3 device to USB 2 port, your device is limited to USB 2 speeds, and it can't draw more power from the port than can be delivered over USB 2. In other words, to get the best performance, make sure that the USB port on your Mac and the USB cable to your device meet or exceed the USB specification of the device itself.
If your Mac doesn't recognize a USB device after you plug it into your Mac:
- Check all connections: Unplug the device from your Mac, then plug it back in, and make sure that all cables and adapters are securely connected at both ends. Test with another cable or adapter, if available.
- Plug the device directly into your Mac instead of a USB hub or other device, and if necessary test with a different USB port on your Mac or device.
- Some devices need their own software, such as drivers or firmware. Others work without additional software. Check with the maker of your device, and install all available Apple software updates as well.
- If your device came with an AC power adapter, use it. Some devices can be powered by the USB port on your Mac. Others need more power than your Mac can provide.
- Restart your Mac.
