Any advice ?
I just tried your test program and cannot replicate your issue using Ubuntu 19.04 and libusb 1.0.22 with an Intel host controller. I don't think re-trying USB transactions is the righ way to go, there is either some issue with your hardware or driver support of your system. Have you tried using a more recent Kernel?
