I've just tested with another 3.0 xhci host, an PCI-e board Renesas Technology Corp. uPD720202 USB 3.0 Host Controller, with ID 1912:0015. When I started capturing video with the video grabber connected to this xhci host the messages where like the ones I received with the ASMedia 1042A. Lots of: xhci_hcd 0000:06:00.0: WARN Successful completion on short TX: needs XHCI_TRUST_TX_LENGTH quirk? But when the video grab hanged it presented the message below once: Apr 23 10:54:31 video-teste kernel: [ 158.931156] xhci_hcd 0000:06:00.0: ERROR Transfer event TRB DMA ptr not part of current TD ep_index 8 comp_code 1 And them flooded my log with the messages below at a rate of tens per second: Apr 23 10:54:31 video-teste kernel: [ 158.931252] xhci_hcd 0000:06:00.0: Looking for event-dma 00000000b9af9250 trb-start 00000000b9af9260 trb-end 00000000b9af9260 seg-start 00000000b9af9000 seg-end 00000000b9af93f0 Apr 23 10:54:31 video-teste kernel: [ 158.936148] xhci_hcd 0000:06:00.0: ERROR Transfer event TRB DMA ptr not part of current TD ep_index 8 comp_code 1 Do you need xhci debugging from this board also?
