When the device is originally enumerated by the USB stack, the USBHUB driver extracts idVendor, idProduct, and bcdDevice from the device descriptor. These three fields are incorporated to generate a USB hardware ID. Note that the vendor, device, and revision numbers are always stored in hexadecimal format. Step 6: Follow the prompts from the installation program to install the drivers. You may have to restart your computer. Step 7: In your Control Panel/Audio Devices, select the playback device. Depending on device, this may be 'Schiit Modi,' 'Schiit Gen 2 USB' or, in the case of older DACs, 'Schiit USB Audio Interface.' USB Audio ASIO driver helps you connect USB audio interfaces to music applications via ASIO at latencies down to 4ms. Features: USB-audio support for ASIO compatible applications like Cubase.

You do not need drivers for Windows 10, MacOS or for Linux distros that support UAC2. These drivers are for legacy Windows support only.

Drivers for Gen 2 and Gen 5

If the system uses an SATA hard drive or drives and no ATAPI devices other than the optical drive you are installing, configure the optical drive as the master device on the secondary ATA channel, leaving the primary ATA channel unused. (Windows can become confused if the primary master device is an optical drive rather than a hard drive.).

For Windows 10: No drivers necessary.
For Windows 8, 7:Schiit USB Gen2 Drivers 1.03

Once you’ve downloaded the drivers:

Step 1: Go to your Downloads folder (or Desktop, or wherever you had Windows put the drivers.)

Step 2: Double-Click on the Schiit_USB_Gen2_1_03.zip file to expand it.

Step 3: Click on the Schiit_USB_Gen2_1_03 folder to open it.

Step 4: Connect the DAC with a standard USB A-B cable, 2M or less in length, with true USB 2.0 rating.

Step 5: Double-click on setup.exe. This begins the driver installation.

Step 6: Follow the prompts from the installation program to install the drivers. You may have to restart your computer.

Step 7: In your Control Panel/Audio Devices, select the playback device. Depending on device, this may be 'Schiit Modi,' 'Schiit Gen 2 USB' or, in the case of older DACs, 'Schiit USB Audio Interface.' You may also have to select the device separately in the player software you are using in order to get output.

Step 8: Enjoy your music!

Drivers for Yggdrasil Gen 3

For Windows 10: No drivers necessary
For Windows 8, 7: Schiit Gen 3 USB Driver (29 MB)

Once you’ve downloaded the drivers:

Step 1: Remove any current Schiit USB drivers before proceeding further.

Step 2: Go to your Downloads folder (or Desktop, or wherever you had Windows put the drivers) and double-click on the Schiit_USB-Gen3_1_06.zip archive to expand it.

Step 3: Click on the folder Schiit_USB-Gen3_1_06 to open it.

Step 4: Connect Yggdrasil with a standard USB A-B cable, 2M or less in length, with true USB 2.0 rating—not 1.1 or 3.0.

Step 5: Double-click on “setup.exe.” This will automatically select the correct driver for your version of Windows.

Step 6: Follow the prompts from the installation program to install the drivers. You may have to restart your computer.

Step 7: In your Control Panel/Audio Devices, select Schiit USB Gen 3 Interface the playback device. You may also have to select the device separately in the player software you are using in order to get output.

Step 8: Enjoy your music!

Note: On some Windows systems, driver downloads will show up as 'Encrypted,' and will not install. In that case, follow this procedure:

a. After unzipping the drivers, you'll have a directory with the driver files inside.

b. Right-clicking on the directory gives a menu with a 'Properties' button on the bottom.

c. Click on Properties, On the first tab, 'General,' click on the 'Advanced' button under 'Attributes.' You will see four checkboxes, the last of which is 'Encrypt contents to secure data.'

d. Uncheck that box and click 'Apply.' Unencrypt for all subdirectories, and proceed with Setup as in Step 5.

This topic is for programmers. If you are a customer experiencing USB problems, see Troubleshoot common USB problems

This topic lists the Microsoft-provided drivers for the supported USB device classes.

• Microsoft-provided drivers for USB-IF approved device classes.
• For composite devices, use USB Generic Parent Driver (Usbccgp.sys) that creates physical device objects (PDOs) for each function.
• For non-composite devices or a function of a composite device, use WinUSB (Winusb.sys).

If you are installing USB drivers: You do not need to download USB device class drivers. They are installed automatically. These drivers and their installation files are included in Windows. They are available in the WindowsSystem32DriverStoreFileRepository folder. The drivers are updated through Windows Update.

If you are writing a custom driver: Before writing a driver for your USB device, determine whether a Microsoft-provided driver meets the device requirements. If a Microsoft-provided driver is not available for the USB device class to which your device belongs, then consider using generic drivers, Winusb.sys or Usbccgp.sys. Write a driver only when necessary. More guidelines are included in Choosing a driver model for developing a USB client driver.

USB Device classes

USB Device classes are categories of devices with similar characteristics and that perform common functions. Those classes and their specifications are defined by the USB-IF. Each device class is identified by USB-IF approved class, subclass, and protocol codes, all of which are provided by the IHV in device descriptors in the firmware. Microsoft provides in-box drivers for several of those device classes, called USB device class drivers. If a device that belongs to a supported device class is connected to a system, Windows automatically loads the class driver, and the device functions with no additional driver required.

Hardware vendors should not write drivers for the supported device classes. Windows class drivers might not support all of the features that are described in a class specification. If some of the device's capabilities are not implemented by the class driver, vendors should provide supplementary drivers that work in conjunction with the class driver to support the entire range of functionality provided by the device.

For general information about USB-IF approved device classes see the USB Common Class Specification

The current list of USB class specifications and class codes is documented in the USB-IF Defined Class Code List.

Device setup classes

Drivers Asahi Optical Usb Devices Drivers

Windows categorizes devices by device setup classes, which indicate the functionality of the device.

Microsoft defines setup classes for most devices. IHVs and OEMs can define new device setup classes, but only if none of the existing classes apply. For more information, see System-Defined Device Setup Classes.

Two important device setup classes for USB devices are as follows:

• USBDevice {88BAE032-5A81-49f0-BC3D-A4FF138216D6}: IHVs must use this class for custom devices that do not belong to another class. This class is not used for USB host controllers and hubs.

• USB {36fc9e60-c465-11cf-8056-444553540000}: IHVs must not use this class for their custom devices. This is reserved for USB host controllers and USB hubs.

The device setup classes are different from USB device classes discussed earlier. For example, an audio device has a USB device class code of 01h in its descriptor. When connected to a system, Windows loads the Microsoft-provided class driver, Usbaudio.sys. In Device Manager, the device is shown under is Sound, video and game controllers, which indicates that the device setup class is Media.
