I'm a little confused here. Do you have one driver matching the composite device, or do you have two drivers, one for each interface? For example, in this snippet: > Opening device 0403:CFF8... > libusbx: error [init_device] device > '\\.\USB#VID_0403&PID_CFF8&MI_01#6&222886B8& > 0&0001' is no longer connected! the "MI_01" implies that you have a separate driver for each interface. In that case, I don't understand the log entries about claiming interface 0 and interface 1. When you have one driver per interface, the composite driver rewrites the descriptors so that each function driver sees a single interface device. -- Tim Roberts, t...@probo.com Providenza & Boekelheide, Inc. ------------------------------------------------------------------------------ Minimize network downtime and maximize team effectiveness.
