This topics in this section describe the class drivers, generic client driver, and the parent composite driver that are provided by Microsoft.
Microsoft-provided USB drivers for controllers and hubs
Microsoft provides these set of drivers:
- For USB host controllers and hubs. For more information, see USB host-side drivers in Windows. You can develop a custom host controller driver that communicates with the USB host controller extension (UCX) driver. For more information, see Developing Windows drivers for USB host controllers.
- For handling common function logic for USB devices. For more information, see USB device-side drivers in Windows.
- For supporting Type-C connectors. For more information, see USB connector manager class extension (UcmCx).
Other Microsoft-provided USB drivers
Device setup class | Microsoft-provided driver and INF | Windows support | Description |
---|---|---|---|
USB | Usbccgp.sys Usb.inf | Windows 8.1 Windows 8 Windows 7 Windows Vista Windows XP | Usbccgp.sys is a parent driver for composite devices that supports multiple functions. For more information, see USB Generic Parent Driver (Usbccgp.sys). |
Biometric | WudfUsbBID.dll WudfUsbBIDAdvanced.inf | Windows 8.1 Windows 8 | Microsoft supports USB biometric devices (fingerprint readers) by providing the Windows Biometric Framework. See the Windows Biometric Framework. |
Media Transfer Protocol Devices | Wpdusb.sys (Obsolete) | Windows Server 2008 Windows Vista Windows Server 2003 Windows XP | Note Starting in Windows 7, Microsoft has replaced the kernel mode component of the Windows Vista USB driver stack (Wpdusb.sys) for Windows Portable Devices (WPD) with the generic Winusb.sys. Microsoft provides the Wpdusb.sys driver to manage portable devices that support the Media Transfer Protocol. See WPD Design Guide. |
USBDevice | Winusb.sys Winusb.inf | Windows 8.1 Windows 8 Windows 7 Windows Vista Windows XP with Service Pack 2 (SP2) | Winusb.sys can be used as the USB device's function driver instead of implementing a driver. See WinUSB. |
Microsoft-provided USB device class drivers
Microsoft provides drivers for several USB device classes approved by USB-IF. These drivers and their installation files are included in Windows. They are available in the WindowsSystem32DriverStoreFileRepository folder.

How to use:
To set serial port, add a property 'ro.kernel.android.gps' and set it equal to your GPS device file.ie. ro.kernel.android.gps=ttyO1
Default baud rate is 9600, to adjust add a property 'ro.kernel.android.gpsttybaud' and set it equal to the needed rate. (4800-115200)ie. ro.kernel.android.gpsttybaud=9600
Default GPS fix rate (interval between position updates) depends on the used device but it is often 1 second. This rate is possibleto modify by property 'ro.kernel.android.gps.max_rate' if your GPS device is able to process UBX protocol. Acceptable property valuemust be from one of two ranges - from 1 to 65 seconds or from 250 to 65000 milliseconds.
Serial GPS driver is able to synchronize system time by the similar way as Internet connection. Property'ro.kernel.android.gps.time_sync' which is greater than zero is taken as threshold in seconds. If difference between system timeand GPS time will grow over given threshold then system time will be set to GPS time with the respect to the current time zone.Threshold should be set to some value from 20 to 60. If property is missing or its value is zero then time synchronizationis turned off.
To add power management for your target product,
cp power-stubs.c power-$(TARGET_PRODUCT).c
and fill in the stubs.Notes:
- If using a USB device make sure you have the necessary kernel modules loaded or built in to the kernel.
- Make sure the permissions on your device file are correct
