Only not clear why SUSPEND happen hear. Is it because of disconnect/connect or reloading g_serial? Is this log recorded when issue seen? Anyway, before SUSPEND and after dwc2 successfully perform transfers on all EP's - ep1in bulk, ep2out bulk and ep3in interrupt. Can you provide dmesg with dwc2 debug prints with exception case inside. > Is this information you need? If need we can gather more info. > Thanks, Minas
