The IUsbInterface interface contains members needed communicate with an
interface of a usb device.

Members| All Members | Methods | Properties | |||
| Icon | Member | Description |
|---|---|---|
 | ActiveEndpoints |
A list of endpoints that have beened opened by this UsbDevice class.
|
 | Close()()()() |
Closes and frees device resources. Once closed the device cannot be reopened. A new UsbDevice class must be obtained using the UsbGlobals class.
|
| Configs |
Gets the available configurations for this UsbDevice |
| ControlTransfer(UsbSetupPacket%, IntPtr, Int32, Int32%) |
Sends/Receives an IO control message to endpoint 0.
|
| ControlTransfer(UsbSetupPacket%, Object, Int32, Int32%) |
Transmits io control message to endpoint 0.
|
| DriverMode |
Returns the DriverMode this USB device is using.
|
| GetDescriptor(Byte, Byte, Int16, IntPtr, Int32, Int32%) |
Gets a specific descriptor from the device. See DescriptorType for more information.
|
| GetDescriptor(Byte, Byte, Int16, Object, Int32, Int32%) |
Gets a specific descriptor from the device. See DescriptorType for more information.
|
| GetLangIDs(array<Int16>[]()[][]%) |
Asking for the zero'th index is special - it returns a string
descriptor that contains all the language IDs supported by the
device. Typically there aren't many - often only one. The
language IDs are 16 bit numbers, and they start at the third byte
in the descriptor. See USB 2.0 specification, section 9.6.7, for
more information on this.
|
| GetString(String%, Int16, Byte) |
Gets a string descriptor from the device.
|
| Info |
Gets the actual device descriptor the the current UsbDevice.
|
| IsOpen |
Gets a value indication if the device handle is valid.
|
| Open()()()() |
Opens/re-opens this USB device instance for communication.
|
| OpenEndpointReader(ReadEndpointID, Int32) |
Opens a Bulk endpoint for reading
|
| OpenEndpointReader(ReadEndpointID, Int32, EndpointType) |
Opens an endpoint for reading
|
| OpenEndpointReader(ReadEndpointID) |
Opens a Bulk endpoint for reading
|
| OpenEndpointWriter(WriteEndpointID) |
Opens a Bulk endpoint for writing
|
| OpenEndpointWriter(WriteEndpointID, EndpointType) |
Opens an endpoint for writing
|
| UsbRegistryInfo |
Gets the UsbRegistry class that opened the device, or null if the device was not opened by the UsbRegistry class.
