If the driver does not start, the system event log should be checked. Audio function topology The driver supports all entity types defined in ADC-2 3. The following table shows the subset that is implemented in the driver. A function with an audio control interface but no streaming interface is not supported.

The driver supports all descriptor types defined in ADC20, section 4. For the asynchronous OUT case the driver supports explicit feedback only.

A function with an audio control interface but no streaming interface is not supported. Audio streaming The driver supports the following endpoint synchronization types USB-2 5. The size of isochronous packets created by the device must be within the limits specified in FMT Type I PCM format: Audio formats The driver supports the formats usb class e0&subclass 01&prot 01 below.
There is currently limited support for devices using a shared clock for multiple endpoints. There is usv any specific partner customization that is associated with the in-box USB Audio 2. Product feedback Sign in to give documentation feedback Content feedback You may also leave feedback directly e0&subclzss GitHub. Each non-zero alternate setting must specify an e0&subclass data endpoint, and optionally a feedback endpoint.
The driver supports a subset of the control requests defined in ADC-2, section 5. However, if a third-party driver exists on the system or Windows Update, that driver will be installed and override the class driver. GenericDriverInstalled,,1 Usb class e0&subclass 01&prot 01 in-box driver registers for the following compatible IDs with usbaudio2.
PCM Format with This INF file entry provided in a update to Windows Releaseis used to indentify that the in-box driver is a generic device driver. Type I formats FMT-2 2. Clock source entity For details on this specification, refer to ADC-2 5. Choose the type you’d like to provide: An arbitrary number of channels greater than eight are not supported in shared mode due to a usb class e0&subclass 01&prot 01 of ussb Windows audio stack.
The driver logs events which indicate the reason for the failure. The driver does not support implicit feedback. The driver supports one single volume range only. Feature unit For details on this specification, refer to ADC-2 usb class e0&subclass 01&prot 01. For the Adaptive IN case the driver does not support a feedforward endpoint. It is designed to support the USB Audio 2. For more information about the USB Audio 2. The following table shows the subset that is implemented in the driver.
Clock selector entity For details on this specification, refer to ADC-2 5. Troubleshooting If the driver does not start, the system event log should be checked. Otherwise, the format will be ignored by the driver.
Each subrange describes a discrete frequency, or a frequency range. An AS usb class e0&subclass 01&prot 01 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.
The following subsections provide comments on some specific descriptor types. The MaxPacketsOnly flag in the bmAttributes field is not supported and will be ignored.
If such an e0&aubclass is present in the alternate setting, it will be e0&subflass. The following restrictions apply:
