Cable watcher wants to clear the Bus Error after A_VBUS_ERR Only works if ID-Pin is present (this is an A-Device) and there has already been a bus erorr. This will not result in any attempt to raise or drop VBus

Cable watcher wants to drop VBus. If ID-Pin is present this is an A-Device and this will result in stopping VBus power-up

Cable watcher wants to assert Bus_request. If ID-Pin is present this is an A-Device and this will result in an attempt to raise VBus. Second attempt to raise VBus causes KErrUsbOtgVbusAlreadyRaised error. If ID-Pin is absent this is a B-Device and this will result in an attempt to use SRP. Recently does nothing

When BusRequest() returns an error, VBus remains low until the errors are cleared by BusDrop() or BusClearErr() calls

Cable watcher wants to assert Bus_request after SRP. If ID-Pin is present this is an A-Device and this will result in an attempt to raise VBus

Cancels the interest of the pending operation of the device's USB service, either starting or stopping. The pending request will run to the completion. The caller of this function receives a status of KErrCancel.

Queries the USB manager to determine if a given class is supported

Connect the Handle to the Server Must be called before all other methods except Version()

Request to be notified of a change in state of the USB device.

Cancel the outstanding device state notification request.

Disable Function Driver Loading.

Enable Function Driver Loading.

Gets the current personality id of the device's USb service

Functions below this point are deprecated and should not be used. Get the current state of the device's USB service. This function is deprecated and has been replaced by the GetServiceState function from version 7.0s onwards.

Gets the textual description of the personality identified by the aPersonalityId. Caller is repsonsible for freeing up memories allocated to aLocalizedPersonalityDescriptor.

Gets the detailed textual description of the personality identified by the aPersonalityId. Caller is repsonsible for freeing up memories allocated to aLocalizedPersonalityDescriptor.

Gets the current device state (eg. powered, configured...).

Get Manufacturer Descriptor

Gets all supported personality ids of the device's USB service.

Gets the property of the personality identified by the aPersonalityId.

Get Product Descriptor

Get the current state of the device's USB service.

Gets supported classes by the given personality identified by the aPersonalityId

Get Supported Languages from USB Device

Register for Host Device Event notifications. The request only completes when the host event occurs. Calling this function the first time initializes Host Events queue

KErrNone - if successful KErrInUse - if there is another outstanding nofitication request for the same session otherwise an error code returned by FDF

Cancel the outstanding FDF Device Event notification request.

Register for Messages notifications The request only completes when the new message arrives. Calling this function the first time initializes Messages queue

Cancel the outstanding Messages notification request.

Informs USB Manager that the client would like to initialte USB session. On A-Device, it results in sending a notification to 'controller' application On B-Device, it may trigger either SRP or HNP sequence depending on the state of VBus

Request to be notified of a change in service state of the USB device. The request only completes when the service state changes.

Cancel the outstanding service state notification request.

Set or reset the mode in which current RUsb session operates. Recent implementation assumes that there is the one and only application which controls USBMAN, all other clients act as listeners to notification requests. Only application which was previously granted 'control' mode is allowed to reset it at later stage. Any calls from other applications will generate an error.

Start the device's USB service. Should not be called if the USB services have already been started Note: Asynchonous Version, outcome returned when the status is completed

Cancels the pending start operation of the device's USB service.

Request to be notified of a change in state of the USB device. This function is deprecated and has been replaced by the DeviceStateNotification function from version 7.0s onwards.

Cancel the outstanding device state notification request. This function is deprecated and has been replaced by the DeviceStateNotificationCancel function from version 7.0s onwards.

Stops the device's USB service. Should not be called if the USB services have not been started. This is the synchronous variant of this function. This function is deprecated- use the asynchronous version.

Stops the device's USB service. Should not be called if the USB services have not been started. This is the asynchronous variant of this function.

Cancels the pending stop operation of the device's USB service.

Try to start the device's USB service. It starts the current personality only if the service is in the idle state. Calling this API while the server is in any other states has no any effect on the service state.

Note: Asynchonous version, outcome returned when the status is completed

Try to stop the device's USB service. It stops the service only if the serice is in the started state. Calling this API while the server is in the other states has no any effect on the service state.

Note: Asynchonous version, outcome returned when the status is completed

Extract the version of the server providing the RUsb API

Simulates memory allocation in the USB Manager. This function is only defined in debug builds.

Checks that the number of allocated cells on the USB Manager's heap is correct. The USB Manager will be panicked if it is not. This function is only defined in debug builds.

Simulates memory allocation failure in the USB Manager. This function is only defined in debug builds.

Marks the end of heap cell checking for the USB Manager. Checks that the number of heap cells allocated since the last __DbgMarkHeap() is aCount; the most common value to pass here is zero. This function is only defined in debug builds.

Marks the start of heap cell checking for the USB Manager. This function is only defined in debug builds.
