Hi Sara, Thank you for your reply. > The xHCI host controller will write a little endian value into the > 32-bit flags portion of the event.

Also, does > the TRB_CYCLE need to be wrapped? I found that the endian change is needed in inc_enq(). But not handle the event correctly. (xhci->event_ring->dequeue->event_cmd is still zero) I will continue to try.
