I have some problems/questions regarding the VMLite XP mode.
How do I install drivers in my xp and how do i check for my driver? The reason i download XP mode is because some games ain't compatiable with windows 7 and on the XP mode, it needs to update driver(?) and i don't know how to check my driver(?).
-Its video driver like nvidia and so.
How do I increase the ram of the XP mode? I have 6gb in my computer and the XP is only 512mb and how about the processor too.
When i insert my thumb drive into my computer, the xp mode doesnt detect thumbdrive how do i fix it?
What is the file VMLiteGuest Additions? I tried to install it but when i start up, it pops out the type in ur username or something which doesnt occur normally.
There is no sound in my XP mode how do i install sounds in it?
How do I completely uninstall one XP mode and delete all the programs in there? Is it right click delete on the workstation? will it be complete remove?
I hope somebody will clarify my doubts, and nevertheless this VMLite is great!!

I also added the 'FTDI USB Serial' device/driver to the USB devices in workstation. This seems to crash the vm. When I start the vm, it opens a window titled 'VMLite XP Mode Starting' as it normally does, but it also opens a second window called 'VMLite XP Mode spawning' which seems to.

Starting with Windows 10, release 1703, a USB Audio 2.0 driver is shipped with Windows. It is designed to support the USB Audio 2.0 device class. The driver is a WaveRT audio port class miniport. For more information about the USB Audio 2.0 device class, see https://www.usb.org/documents?search=&type%5B0%5D=55&items_per_page=50.

The driver is named: usbaudio2.sys and the associated inf file is usbaudio2.inf.

The driver will identify in device manager as 'USB Audio Class 2 Device'. This name will be overwritten with a USB Product string, if it is available.

The driver is automatically enabled when a compatible device is attached to the system. However, if a third-party driver exists on the system or Windows Update, that driver will be installed and override the class driver.

Architecture

usbaudio2.sys fits within the wider architecture of Windows USB Audio as shown.

Related USB specifications

The following USB specifications define USB Audio and are referenced in this topic.

USB-2 refers to the Universal Serial Bus Specification, Revision 2.0
ADC-2 refers to the USB Device Class Definition for Audio Devices, Release 2.0.
FMT-2 refers to the Audio Data Formats specification, Release 2.0.

The USB-IF is a special interest group that maintains the Official USB Specification, test specifications and tools.

Audio formats

The driver supports the formats listed below. An alternate setting which specifies another format defined in FMT-2, or an unknown format, will be ignored.

Type I formats (FMT-2 2.3.1):

PCM Format with 8.32 bits per sample (FMT-2 2.3.1.7.1)
PCM8 Format (FMT-2 2.3.1.7.2)
IEEE_FLOAT Format (FMT-2 2.3.1.7.3)

Type III formats (FMT-2 2.3.3 and A.2.3):

IEC61937_AC-3
IEC61937_MPEG-2_AAC_ADTS
IEC61937_DTS-I
IEC61937_DTS-II
IEC61937_DTS-III

Feature descriptions

Audio function topology

The driver supports all entity types defined in ADC-2 3.13.

Each Terminal Entity must have a valid clock connection in compatible USB Audio 2.0 hardware. The clock path may optionally include Clock Multiplier and Clock Selector units and must end in a Clock Source Entity.

The driver supports one single clock source only. If a device implements multiple clock source entities and a clock selector, then the driver will use the clock source that is selected by default and will not modify the clock selector’s position.

A Processing Unit (ADC-2 3.13.9) with more than one input pin is not supported.

An Extension Unit (ADC-2 3.13.10) with more than one input pin is not supported.

Cyclic paths in the topology are not allowed.

Audio streaming

The driver supports the following endpoint synchronization types (USB-2 5.12.4.1):

Asynchronous IN and OUT
Synchronous IN and OUT
Adaptive IN and OUT

For the asynchronous OUT case the driver supports explicit feedback only. A feedback endpoint must be implemented in the respective alternate setting of the AS interface. The driver does not support implicit feedback.

There is currently limited support for devices using a shared clock for multiple endpoints.

For the Adaptive IN case the driver does not support a feedforward endpoint. If such an endpoint is present in the alternate setting, it will be ignored. The driver handles the Adaptive IN stream in the same way as an Asynchronous IN stream.

The size of isochronous packets created by the device must be within the limits specified in FMT-2.0 section 2.3.1.1. This means that the deviation of actual packet size from nominal size must not exceed +/- one audio slot (audio slot = channel count samples).

Descriptors

An audio function must implement exactly one AudioControl Interface Descriptor (ADC-2 4.7) and one or more AudioStreaming Interface Descriptors (ADC-2 4.9). A function with an audio control interface but no streaming interface is not supported.

The driver supports all descriptor types defined in ADC-2, section 4. The following subsections provide comments on some specific descriptor types.

Class-Specific AS interface descriptor

For details on this specification, refer to ADC-2 4.9.2.

An AS interface descriptor must start with alternate setting zero with no endpoint (no bandwidth consumption) and further alternate settings must be specified in ascending order in compatible USB Audio 2.0 hardware.

An alternate setting with a format that is not supported by the driver will be ignored.

Each non-zero alternate setting must specify an isochronous data endpoint, and optionally a feedback endpoint. A non-zero alternate setting without any endpoint is not supported.

The bTerminalLink field must refer to a Terminal Entity in the topology and its value must be identical in all alternate settings of an AS interface.

The bFormatType field in the AS interface descriptor must be identical to bFormatType specified in the Format Type Descriptor (FMT-2 2.3.1.6).

For Type I formats, exactly one bit must be set to one in the bmFormats field of the AS interface descriptor. Otherwise, the format will be ignored by the driver.

To save bus bandwidth, one AS interface can implement multiple alternate settings with the same format (in terms of bNrChannels and AS Format Type Descriptor) but different wMaxPacketSize values in the isochronous data endpoint descriptor. For a given sample rate, the driver selects the alternate setting with the smallest wMaxPacketSize that can fulfill the data rate requirements.

Type I format type descriptor

For details on this specification, refer to FMT-2 2.3.1.6.

The following restrictions apply:

Format	Subslot size	Bit resolution
Type I PCM format:	1 <= bSubslotSize <= 4	8 <= bBitResolution <= 32
Type I PCM8 format:	bSubslotSize 1	bBitResolution 8
Type I IEEE_FLOAT format:	bSubslotSize 4	bBitResolution 32
Type III IEC61937 formats:	bSubslotSize 2	bBitResolution 16

Class-Specific AS isochronous audio data endpoint descriptor

For details on this specification, refer to ADC-2 4.10.1.2.

The MaxPacketsOnly flag in the bmAttributes field is not supported and will be ignored.

The fields bmControls, bLockDela
