NTL I found that little gem: https://www.fclose.com/linux-kernels/594677/usb-io_ti-add-heartbeat-to-keep-idle-ep-416-ports-from-disconnecting-linux-4-3/ The behavior would fit (any way to check that the heartbeat is active ?). Casten Schmidt ask me to look into /sys/kernel/debug/dynamic_debug/control before i start to debug the whole usb part, is that below expected behavior ?
