Members| All Members | Methods | Properties | Fields | Events | |
| Icon | Member | Description |
|---|---|---|
 | ActiveEndpoints |
A list of endpoints that have beened opened by this UsbDevice class.
|
 | AllDevices |
Gets a list of all available USB devices (WinUsb, LibUsb, Linux LibUsb v1.x).
|
| AllLibUsbDevices |
Gets a list of all available libusb-win32 USB devices.
|
| AllWinUsbDevices |
Gets a list of all available WinUSB USB devices.
|
 | Close()()()() |
Closes the UsbDevice and disposes any ActiveEndpoints.
|
| Configs |
Gets all available configurations for this UsbDevice |
| ControlTransfer(UsbSetupPacket%, IntPtr, Int32, Int32%) |
Transmits control data over a default control endpoint.
|
| ControlTransfer(UsbSetupPacket%, Object, Int32, Int32%) |
Transmits control data over a default control endpoint.
|
| DriverMode |
Returns the DriverMode this USB device is using.
|
| Exit()()()() |
De-initializes the USB driver.
|
 | ForceLibUsbWinBack |
Setting this field to trueTruetrue will force LibUsbDotNet to use the Libusb-1.0 Windows-backend driver. For platforms other than windows, this setting has no effect.
|
| GetAltInterfaceSetting(Byte, Byte%) |
Gets the selected alternate interface of the specified interface.
|
| GetConfiguration(Byte%) |
Gets the USB devices active configuration value.
|
| GetDescriptor(Byte, Byte, Int16, IntPtr, Int32, Int32%) |
Gets a descriptor from the device. See DescriptorType for more information.
|
| GetDescriptor(Byte, Byte, Int16, Object, Int32, Int32%) |
Gets a 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.
|
| HasLibUsbDriver | Obsolete.
True if the LibUsb driver is found on the system.
|
| HasLibUsbWinBackDriver |
True if the libusb-1.0 API is available.
|
| HasWinUsbDriver |
True if the WinUSB API is available.
|
| Info |
Gets the actual device descriptor the the current UsbDevice.
|
| IsLinux |
Returns true if the system is a linux/unix-like operating system.
|
| IsOpen |
Gets a value indication if the device handle is valid.
|
| KernelType |
Gets the kernel driver type in use by LibUsbDotNet.
If NativeLibUsb is returned, LibUsbDotNet using using its
native kernel driver. Basic usb device information is retreived from the windows registry
which reduces USB IO overhead.
If LegacyLibUsb is returned, LibUsbDotNet is using the orginal kernel
available at the libusb-win32.sourceforge.net page and true windows registry support
is unavailable.
Under linux, MonoLibUsb is always returned.
|
| KernelVersion |
Gets the kernel driver version in use by LibUsbDotNet.
if BcdLibUsbDotNetKernelMod is non-zero then the kernel driver is native. |
| LastErrorNumber |
Returns the last error number reported by LibUsbDotNet.
|
| LastErrorString |
Returns the last error string reported by LibUsbDotNet.
|
| Open()()()() |
Opens the USB device handle.
|
| OpenEndpointReader(ReadEndpointID) |
Opens a Bulk endpoint for reading
|
| OpenEndpointReader(ReadEndpointID, Int32) |
Opens a Bulk endpoint for reading
|
| OpenEndpointReader(ReadEndpointID, Int32, EndpointType) |
Opens an endpoint for reading
|
| OpenEndpointWriter(WriteEndpointID) |
Opens a Bulk endpoint for writing
|
| OpenEndpointWriter(WriteEndpointID, EndpointType) |
Opens an endpoint for writing
|
| OpenUsbDevice(UsbDeviceFinder) |
Opens the usb device that matches the UsbDeviceFinder.
|
| OpenUsbDevice(Predicate<(Of <<'(UsbRegistry>)>>)) |
Opens the usb device that matches the find predicate.
|
| OpenUsbDevice(Guid%, UsbDevice%) |
Opens a WinUsb device by its DeviceInterfaceGUID.
|
| OSVersion |
Gets a OperatingSystem object that contains the current platform identifier and version number.
|
 | UsbErrorEvent |
Global static error event for all Usb errors.
|
| UsbRegistryInfo |
Gets the UsbRegistry class that opened the device, or null if the device was not opened by the UsbRegistry class.
|
Remarks
This class is compatible with WinUSB, LibUsb-Win32, and linux libusb v1.x.
Platform independent applications should only use usb device members from this class.
If more functionality is required, it is up to the application to handle multi-driver
and/or multi-platfrom requirements.
