USBDeviceControlIn Method (Byte, Byte, Int32, Int32, Int32)

Initiates a control transfer over the default control endpoint. The request should have an IN direction (specified by the highest bit of the requestType parameter). A buffer to receive the data is automatically created by this method.

Namespace:  MadWizard.WinUSBNet
Assembly:  WinUSBNet (in WinUSBNet.dll) Version: 2.0.0.0 (2.0.0.0)
Syntax
Copy
public byte[] ControlIn(
	byte requestType,
	byte request,
	int value,
	int index,
	int length
)

Parameters

requestType
Type: SystemByte
The setup packet request type. The request type must specify the IN direction (highest bit set).
request
Type: SystemByte
The setup packet device request.
value
Type: SystemInt32
The value member in the setup packet. Its meaning depends on the request. Value should be between zero and 65535 (0xFFFF).
index
Type: SystemInt32
The index member in the setup packet. Its meaning depends on the request. Index should be between zero and 65535 (0xFFFF).
length
Type: SystemInt32
Length of the data to transfer. A buffer will be created with this length and the length member of the setup packet will be set to this length.

Return Value

Type: Byte
A buffer containing the data transfered.
Remarks
This routine initially allocates a buffer to hold the length bytes of data expected from the device. If the device responds with less data than expected, this routine will allocate a smaller buffer to copy and return only the bytes actually received.
