  1. For CMI873x or CMI876x series, C-Media no longer support Win10 driver. For CMI878x, CM88xx, or USB Audio series, please contact your product vendor to get customized Win10 driver. However, if your product didn't apply customized driver when you purchased, you can then just use Win10 in box standard driver.
  2. Bring up drivers. USB Function driver bring-up is only required if you support USB Function mode. If you previously implemented a USB Function driver for a USB micro-B connector, describe the appropriate connectors as USB Type-C in the ACPI tables for the USB Function driver to continue working.

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

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.

  1. Go to Settings > Device Options and look for a Developer Options menu. If it's not there, do the following:

    a. Go to Settings > Device Options > About Fire Tablet.b. Tap your Serial Number seven times.c. Return to Device Options. A new menu appears called 'Developer Options.'

  2. Tap Developer options. (2013 models might call this option 'Security.')
  3. Set Developer options and USB debugging to ON.
  • If you have a Kindle Fire 1st Generation, ADB is enabled by default.

Step 2: Install the Kindle Fire Driver (Windows Only)

  1. If you're using Windows, download this Kindle Fire driver: kindle_fire_usb_driver.zip.
  2. After downloading the file, extract the contents into a new folder and double-click the Fire_Devices ABD drivers file.
  3. Proceed through the installation wizard screens to install the driver.

Step 3: Install Android Studio

ADB is available on your computer when you install Android Studio. If you don't already have Android Studio, download and install Android Studio. If you're not using Android Studio, you need to download and install Android SDK platform tools.

Step 4: Connect Your Fire Device to Your Computer with a USB Cable

  1. Using a USB cable, connect your Fire tablet to a USB port on your computer.

    Note that Fire tablets can treat the USB with different transfer options. After connecting the USB cable, swipe down from the top of your tablet to see the USB option used. You might see various notifications, including the USB connection type that was used when you connected the cable. The relevant notification is highlighted in the screenshot below.

    If you don't see 'Connected as Media Device', press Tap for other USB options. Then select Media device (MTP). Later Fire OS versions have a different interface here. If you're using Fire OS 7, select File Transfer.

    Note: If your USB is connected as a Camera (PTP), Android Studio won't recognize the tablet as a device in Android Studio.

    If you don't see the USB connection type in the above notifications, go to Settings > Device Options > Developer Options > USB computer connection. Set this to Media device (MTP). For Fire OS 7, select File Transfer.

  2. When the Allow USB debugging? dialog appears on your tablet, tap OK.

  3. Open Android Studio and look for the device to appear in devices drop-down menu:

    The device's name will use the android.os.Build.MODEL property for the device. KFSUWI refers to Fire HD 10 (2017) tablet. You can see a list of build model names in the Identifying Fire Tablet Devices.

    If you have not selected the 'Allow USB Debugging' dialog on your tablet, the name 'Unknown device' will appear in the devices drop-down menu in Android Studio until you allow debugging.

  4. With the tablet connected, you can now run your app on your tablet by clicking the Run App button in Android Studio.

If you run into issues, see the Troubleshooting section below.

Check for Device Connections Using ADB (Optional)

Instead of looking in the devices menu in Android Studio, you can also use some ADB terminal commands to confirm that your device is connected. ADB is useful for performing many other operations as well, such as entering sandbox mode or installing other assets. Follow these two sections:

If you skip adding ADB to your PATH, you can also Check for Connected Devices If ADB Isn't In Your PATH.

Add ADB to Your PATH

First, add ADB to your PATH so you can more easily run ADB commands. (Your PATH is an environment variable used to specify the location of the program's executable. If you don't add ADB to your PATH, running ADB commands will require you to browse to the <Android SDK>/platform-tools directory to run adb.)

Devices
Tip: You can check whether ADB is already added to your PATH by typing adb version from a terminal or command prompt. If you get back version information, then ADB is in your PATH. If the response says adb is an unrecognized command, ADB is not in your PATH.

To add ADB to your PATH on Mac:

  1. Get the path to your Android SDK platform-tools directory:

    1. Open Android Studio and click the SDK Manager button .The location to your Android SDK appears near the top next to Android SDK Location. For example: /Users/<your username>/Library/Android/sdk

      If this is your first time opening Android Studio, there isn't an SDK Manager button. Instead, at the Welcome to Android Studio prompt, click Configure > SDK Manager and provide the location to the Android SDK.

    2. Copy the path to the SDK and paste it somewhere convenient, such as a text editor.
    3. Add /platform-tools to the end of the path you copied in the previous step. ('platform-tools' is the directory containing the ADB executable.)
    4. Copy the full path to your clipboard.
  2. Use the following command to add ADB to your .bash_profile. Replace <your username> with your actual username. Also, make sure the path points to your Android SDK.

    Your .bash_profile file is usually in your user directory, which you can find by typing cd ~ (change to your user directory). Then type ls -a (list all) to show all files, including hidden ones.

    If the file isn't there, simply create one. You can then type open .bash_profile to see the paths listed.

    After you add this PATH to your bash profile, you should see the following in your .bash_profile file:

    (Only instead of johndoe, you will see your own username.)

  3. Fully restart any terminal sessions, and then type adb. If you successfully added ADB to your path, you will see ADB help info rather than 'command not found.'

To add ADB to your PATH on Windows:

  1. Get the path to your Android SDK platform-tools directory:

    1. Open Android Studio and click the SDK Manager button .

      The location to your Android SDK appears near the top next to Android SDK Location. For example: C:Users<your user name>AppDataLocalAndroidSdk

      If this is your first time opening Android Studio, there isn't an SDK Manager button. Instead, at the Welcome to Android Studio prompt, click Configure > SDK Manager and provide the location to the Android SDK.

    2. Copy the path to the SDK and paste it somewhere convenient, such as a text editor.
    3. Add /platform-tools to the end of the path you copied in the previous step. ('platform-tools' is the directory containing the ADB executable.)
    4. Copy the full path to your clipboard.
  2. Click your computer's search button (next to Start) and type view advanced system settings.
  3. Click View advanced system settings.
  4. When the System Settings dialog opens, click the Environment Variables button.
  5. Under System Variables (the lower pane), select Path and click Edit.
  6. Do one of the following:

    • On Windows 7 or 8, move your cursor to the farthest position on the right, type ; and then press Ctrl+V to insert the path to your SDK that you copied earlier. It may look like this: ;C:Users<your user name>AppDataLocalAndroidSdkplatform-tools. Click OK on each of the three open dialog boxes to close them.
    • On Windows 10, click the New button and add this location.
  7. Restart any terminal sessions, and then type adb. If you successfully added ADB to your path, you will see ADB help info rather than 'command not found.'

Check for Connected Devices

  1. Assuming ADB is added to your PATH, run the following commands:

  2. Confirm that the serial number for your Fire tablet appears in the list of devices. For example:

    On your tablet, your device's serial number is located under Settings > Device Options.

Check for Connected Devices If ADB Isn't In Your PATH

If your terminal doesn't recognize adb as a command (that is, you didn't add ADB to your PATH), you might have to run the commands from the SDK directory that contains ADB.

  1. In Android Studio go to Tools > SDK Manager.
  2. In the SDK Manager dialog box, copy the Android SDK Location.
  3. Browse to this location in your terminal or command prompt. For example:

    Mac

    Windows

    Then go into the platform-tools directory:

    The platform-tools directory contains adb.

  4. Now run the ADB commands as follows:

    Mac:

    Windows:

    The response should list your device's serial number. For example:

    If your Fire tablet is still not detected, you may need to reboot your computer or log out and back in for the changes to take effect.

Troubleshooting
