I believe this is a simplified design for the isochronous OUT transfer. Technically it may receive less bytes than the wMaxPacketSize of the ISOC OUT Endpoint. This may have something to do with limitation of libusb.sys' isochronous capability as well. It is not as good as libusbK.sys. libusb-win32 currently only supports fixed user-defined ISOC packet size per transfer. -- Xiaofan ------------------------------------------------------------------------------ Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.
