Yes, this is a subtlety in WinUSB that libusbx does not properly handle. When you send a control request, libusbx finds the first valid interface handle in its list and uses that. That does not work for INTERFACE requests. It would have to search for the MATCHING interface handle. -- Tim Roberts, t...@probo.com Providenza & Boekelheide, Inc. ------------------------------------------------------------------------------ Sponsored by Intel(R) XDK Develop, test and display web and hybrid apps with a single code base.
