LibUsbDotNet Changelog

What's new in LibUsbDotNet 2.2.8

Feb 8, 2011
  • Fixed issue with DataReceived event.
  • When disabling the DataRecevied event, the property would return before the action had been fully carried out.
  • Fixed memory leak in device list function.
  • An allocated GCHandle was not freed in the device listing functions resulting in a application memory leak.

New in LibUsbDotNet 2.2.7 (Aug 25, 2010)

  • Fixed libusb-1.0 support.
  • This was broken when ISO endpoint support was added.
  • HasLibUsbDriver()()() property
  • This property will always return true.
  • Fixed 32bit applications not running on 64bit operating systems. (Windows)
  • If LibUsbDotNet is compiled as Win32 instead of Any CPU it would not work on 64bit operating systems with libusb-win32.
  • Updated InfWizard with embedded libusb-win32 v1.2.1 driver resource package.
  • Updated default UsbEndpointBase.MaxReadWrite changed back to 65536. This is the limit at which libusbdotnet begins splitting transfers.

New in LibUsbDotNet 2.2.4 (Mar 16, 2010)

  • Fixed Bug ID: 2969931 - Linux xbuild issue.
  • The xbuild utility failed to build the LibUsbDotNet.sln. This was caused by an invalid resource in the InfWizard application and a casting issue for function that take a Predicate as a parameter.
  • Fixed Bug ID: 2956665 - UsbDeviceFinder fails to find VID and PIDs > 0x7FFF.
  • USB devices that have VID or PIDs greater than 0x7FFF are not found by the UsbDeviceFinder class.
  • Added UsbDevice.Exit()()() method.
  • This was added to support the Libusb-1.0 windows backend port. If the usb device is using Libusb-1.0, this method must be called before the application exits.
  • Added Asynchronous transfer functions to UsbEndpointBase.
  • For more details see the NewAsyncTransfer()()() and SubmitAsyncTransfer()()() functions in the UsbEndpointBase class.
  • Added Low-level .NET MonoLibUsb API for Libusb-1.0.
  • The low-level MonoLibUsb API (Libusb-1.0) is supported on many platforms including windows via the Libusb-1.0 windows-backend port.
  • Unlike the LibUsbDotNet API, MonoLibUsb has full support for all Libusb-1.0 functions.
  • Added UsbRegistry.ForceSetupApi option.
  • This option forces LibUsbDotNet to gather extra device information via the windows setup api for devices using drivers that do not support the setupapi.
  • Added UsbDevice.ForceLibUsbWinBack option.
  • This option forces LibUsbDotNet to use only the Libusb-1.0 windows backend driver.

New in LibUsbDotNet 2.2.3 (Mar 16, 2010)

  • Removed - GetConfiguration call in UsbDevice.Open method.
  • The UsbDevice.Open()()() method requests the usb devices current configuration upon opening. This causes problems in some situations.
  • Added IUsbDevice.ResetDevice()()() method.
  • Fixed Bug ID: 2937372 - Read Failed:WaitHandle.WaitOne missing member exception.
  • If .NET 3.5 is not installed, a System.Threading.WaitHandle.WaitOne missing member exception is thrown. LibUsbDotNet should not require the 3.5 runtime. It should work with 2.0 and greater.
  • Fixed Bug ID: 2935627 - Stack overflow when reading an ep that does not exists.
  • If an attempt is made to open and transmit to a non-existent endpoint a stack overflow occurs. Expected behavior is to throw an exception.
  • Fixed Bug ID: 2935456 - UsbDevice.KernelType property not set correcty.
  • [Windows Only] If the UsbDevice.KernelType is accessed when no device are connected it does not update properly when a device is connected.
  • v2.2.2 (01/19/2010)

New in LibUsbDotNet 2.2.2 (Mar 16, 2010)

  • Fixed Bug ID: 2934547 - DeviceNotifier not working.
  • On Linux like OSes the DeviceNotifier never fires events. On Windows, a DllNotFound exception is thrown.
  • Fixed Bug ID: 2933530 - Composite WinUSB not found.
  • WinUSB interfaces that are part of a composite device do not appear in the WinUsbRegistry.DeviceList.

New in LibUsbDotNet 2.2.1 (Mar 16, 2010)

  • Fixed Bug ID: 2930836 - [OSX PPC] GetDescriptor request fails.
  • On big-endian platforms, the descriptor type and index bytes are reversed.
  • Fixed Bug ID: 2927179 - Wrong versioning. LibUsbDotNet 2.2.0 all AssemblyInfo.cs contains [assembly:AssemblyVersion("2.1.0.13")]
  • Updated Benchmark application: Removed all calls to Control.Invoke.
  • The benchmark application now uses a timer control to periodically update the display instead of "Invoking" an update everytime data is transferred. This provides a more accurate benchmark reading as well as a work-a-round for Mono .NET runtimes on platforms that do not properly implement the Control.Invoke method.
  • Removed LINUX compiler option.
  • The LINUX compiler option is no longer used. LibUsbDotNet (v2.2.1 and above) is fully platform independent.

New in LibUsbDotNet 2.2.0 (Mar 16, 2010)

  • Added Linux support.
  • LibUsbDotNet supports linux via the linux libusb v1.x driver.
  • Updated UsbDevice.OpenEndpointReader and UsbDevice.OpenEndpointWriter members to first lookup the endpoint descriptor for the current configuration.
  • If an attempt is made to open an endpoint on a unconfigured device (GetConfiguration = 0) an exception is thrown.
  • If an attempt is made to open a non-existent or invalid endpoint an exception is thrown.
  • Added endpoint descriptor information to UsbEndpointBase class.
  • A New property, 'EndpointInfo' is available from the UsbEndpointBase class.
  • Removed Depricated UsbGlobals class.
  • The UsbGlobals class has been rendered obsolete and will be removed in future release. Update your code you use the UsbDevice class instead.

  • Fixed Bug ID: 2853283 - Infwizard exception thrown on load
  • The InfWizard throws an exception when loaded.
  • Added support for the genuine libusb-win32 kernel driver.
  • If the LibUsbDotNet native kernel driver is not detected it falls back to the original libusb-win32 kernel driver. Using the native driver is recommended.
  • Added static open method to the LibUsbDevice class.
  • Opens a libUsb device from a user suppiled device filename.
  • public static bool Open(string deviceFilename, out LibUsbDevice usbDevice)
  • Added static open method to the WinUsbDevice class.
  • Opens a WinUSB device from a user suppiled device path (symbolic link).
  • public static bool Open(string devicePath, out WinUsbDevice usbDevice)
