Hi, after more testing, I found out that only the first 3 control URBs complete successfully. I tried to duplicate the first GET_DESCRIPTOR(CONFIG) request, and the second one which worked before now fails. If I unplug/replug the device, the first GET_DESCRIPTOR(DEVICE) request sent to device 0 from hub_port_init fails:
