Maybe you want to try out libusbx git to see if that helps. https://github.com/libusbx/libusbx Does your device have an HID as one of the interface? The following commit fixes an issue after 1.0.14 release. Take note 1.0.13 and 1.0.14 release are basically the same. https://github.com/libusbx/libusbx/commit/fdff665a44169eda702a1267a3bbb4501d6bb3ee -- Xiaofan ------------------------------------------------------------------------------ Monitor your physical, virtual and cloud infrastructure from a single web console.
