The device identifier

DataOutL(TInt, TUint8, TUint16, const TDesC8 &)

void	DataOutL	(	TInt	aConnID,
			TUint8	aReportID,
			TUint16	aInterface,
			const TDesC8 &	aReport
		)	[pure virtual]

Request to send data to a device. There are no responses to this report from device.

Since: S60 v5.0

Parameters

TInt aConnID	The device identifier
TUint8 aReportID	The specific report required
TUint16 aInterface	The interface we want to send the report to
const TDesC8 & aReport	The report payload to be sent to the device

GetIdleL(TInt, TUint8, TUint16)

void	GetIdleL	(	TInt	aConnID,
			TUint8	aReportID,
			TUint16	aInterface
		)	[pure virtual]

Request for the current idle rate of a report from the device. The response will be recevied via the CHidTransport::DataIn function

Since: S60 v5.0

Parameters

TInt aConnID	The device identifier
TUint8 aReportID	The specific report to be queried
TUint16 aInterface	The interface we want to query for idle rate

GetProtocolL(TInt, TUint16)

			TUint16	aInterface
		)	[pure virtual]

Request for the current device report protocol. The protocol will be received as a control report via the CHidTransport::DataIn function

Since: S60 v5.0

Parameters

TInt aConnID	The device identifier
TUint16 aInterface	The interface we want to get the protocol from

GetReportL(TInt, TUint8, TUint8, TUint16, TUint16)

			TUint8	aReportType,
			TUint8	aReportID,
			TUint16	aInterface,
			TUint16	aLength
		)	[pure virtual]

Request for a device report. The data will be received as a control report via the CHidTransport::DataIn function

Since: S60 v5.0

Parameters

TInt aConnID	The device identifier
TUint8 aReportType	The type of report (input/output/feature) requested
TUint8 aReportID	The specific report required
TUint16 aInterface	The interface we want the report from
TUint16 aLength	The expected length of the report buffer

ProductIdL(TInt)

TUint

ProductIdL

(

TInt

aConnID

)

[pure virtual]

Request for the product identifier for the given device.

Since: S60 v5.0

Parameters

TInt aConnID

The device identifier

SetIdleL(TInt, TUint8, TUint8, TUint16)

void	SetIdleL	(	TInt	aConnID,
			TUint8	aDuration,
			TUint8	aReportID,
			TUint16	aInterface
		)	[pure virtual]

Request to set the current idle rate for a report on the device. The response will be received via the CHidTransport::CommandResult function

Since: S60 v5.0

Parameters

TInt aConnID	The device identifier
TUint8 aDuration	The time period between idle reports (4ms per bit. An interval of 0 disables idle reports so that Interrupt reports are only ever received when the reported data has changed
TUint8 aReportID	The specific report to be queried
TUint16 aInterface	The interface we want to query for idle rate

SetProtocolL(TInt, TUint16, TUint16)
