This topic describes the device-specific registry entries.

Wacom USB tablets are handled by a special kernel driver (wacom), which uses complex sequences of evdev events to report the input. The only X driver capable of handling that input fully is. X.Org driver for Wacom devices. Contribute to linuxwacom/xf86-input-wacom development by creating an account on GitHub.

1. Find the Realtek device and right-click or long press on it. Select Update Driver from the context menu. Select the Browse my computer for driver software button. It should default to your Documents folder, if this is where you saved the drivers then just select the Next button.
2. The audio output and input device can be selected in System Sound settings. Make sure they are connected and turned on.

Find device information after it enumerates on Windows

View the device interface GUID, Hardware Id, and device class information about your device

1. Find this registry key and note the DeviceInstance value:

   HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlDeviceClasses

2. Find the device instance registry key and get the device interface GUID:

   HKEY_LOCAL_MACHINESYSTEMCurrentControlSetEnumUSB<hardware id><instance id>Device Parameters

3. Under the device instance key, note the device class, subclass, and protocol codes:

   HKEY_LOCAL_MACHINESYSTEMCurrentControlSetEnumUSB

Registry settings for configuring USB driver stack behavior

The registry entries described in this topic are found under this key:

In the vvvvpppprrrrr key,

• vvvv is a 4-digit hexadecimal number that identifies the vendor
• pppp is a 4-digit hexadecimal number that identifies the product
• rrrr is a 4-digit hexadecimal number that contains the revision number of the device.

The vendor ID, product ID, and revision number values are obtained from the USB device descriptor.The following table describes the possible registry entries for the vvvvpppprrrrr key. The USB driver stack considers these entries as read-only values.

Registry entry	Description	Possible values
osvc REG_BINARY Supported on Windows XP and later versions.	Indicates whether the operating system queried the device for Microsoft-Defined USB Descriptors. If the previously-attempted OS descriptor query was successful, the value contains the vendor code from the OS string descriptor.	0x0000: The device did not provide a valid response to the Microsoft OS string descriptor request. 0x01xx: The device provided a valid response to the Microsoft OS string descriptor request, where xx is the bVendorCode contained in the response.
IgnoreHWSerNum REG_BINARY Supported on Windows Vista and later versions.	Indicates whether the USB driver stack must ignore the serial number of the device.	0x00: The setting is disabled. 0x01: Forces the USB driver stack to ignore the serial number of the device. Therefore, the device instance is tied to the port to which the device is attached.
ResetOnResume REG_BINARY Supported on Windows Vista and later versions.	Indicates whether the USB driver stack must reset the device when the port resumes from a sleep cycle.	0x0000: The setting is disabled. 0x0001: Forces the USB driver stack to reset a device on port resume.
