Hi Mathias, I am implementing USB2 EHSET SINGLE_STEP_SET_FEATURE Test for XHCI port, (see ehset_single_step_set_feature for EHCI), it needs to set IOC for setup packet, and software waits 15 seconds before DATA + STATUS stage. After porting such design for XHCI, it triggers above warning, and returns -ESHUTDOWN for URB. Any reasons why we don't allow completion interrupt for SETUP stage? Thanks.
