Please see http://sourceforge.net/apps/mediawiki/libusbx/index.php?title=Windows#Known_Restrictions: "WinUSB cannot be used to set a device configuration that is different from the default one." This is a limitation of Microsoft's WinUSB driver, as documented at http://msdn.microsoft.com/en-us/library/windows/hardware/ff537060%28v=vs.85%29.aspx: "WinUSB supports only the first configuration." Note that we are in the process to integrate support for other drivers than WinUSB, that shouldn't have such a limitations. > If I force the code to follow the else branch (by removing the if), I > get it working further but in the end I would get it stopped on trying > to claim some interfaces. There was a patch submitted recently to at least allow the sending of the set configuration request even when using WinUSB, in case there was some use on the device side for such a message. We plan to look into adding such a feature when we add support for the other drivers.
