Constructor Detail

UsbControlPipeImp

public UsbControlPipeImp()

Constructor.

UsbControlPipeImp

public UsbControlPipeImp(UsbEndpointImp ep)

Constructor.

Parameters:

ep - The UsbEndpointImp.

UsbControlPipeImp

public UsbControlPipeImp(UsbControlPipeOsImp pipe)

Constructor.

Parameters:

pipe - The platform-dependent pipe implementation.

UsbControlPipeImp

public UsbControlPipeImp(UsbEndpointImp ep,
                         UsbControlPipeOsImp pipe)

Constructor.

Parameters:

ep - The UsbEndpointImp.

pipe - The platform-dependent pipe implementation.

Method Detail

syncSubmit

public int syncSubmit(byte[] data)
               throws UsbException

Control pipes cannot handle raw byte[] submissions.

Since Control pipes require a setup packet, raw byte[]s are disallowed. This will throw UsbException.

Specified by:

syncSubmit in interface UsbPipe

Overrides:

syncSubmit in class UsbPipeImp

Parameters:

data - The buffer to use.

Returns:

The number of bytes actually transferred.

Throws:

UsbException - Raw byte[]s cannot be used on Control pipes.

asyncSubmit

public UsbIrp asyncSubmit(byte[] data)
                   throws UsbException

Control pipes cannot handle raw byte[] submissions.

Since Control pipes require a setup packet, raw byte[]s are disallowed. This will throw UsbException.

Specified by:

asyncSubmit in interface UsbPipe

Overrides:

asyncSubmit in class UsbPipeImp

Parameters:

data - The buffer to use.

Returns:

A UsbIrp representing the submission.

Throws:

UsbException - Raw byte[]s cannot be used on Control pipes.

usbIrpToUsbIrpImp

protected UsbIrpImp usbIrpToUsbIrpImp(UsbIrp irp)
                               throws UsbException

Convert a UsbControlIrp to UsbControlIrpImp.

If the UsbIrp is not a UsbControlIrp, a UsbException is thrown. This does not use the superclass method.

Overrides:

usbIrpToUsbIrpImp in class UsbPipeImp

Parameters:

irp - The UsbControlIrp to convert.

Throws:

UsbException - If the UsbIrp is not ready for submission.
