From: Jens Glathe <jens.glathe@xxxxxxxxxxxxxxxxxxxxxx> commit 4f547472380136718b56064ea5689a61e135f904 upstream. This appears to fix the error: "xhci_hcd <address>; ERROR Transfer event TRB DMA ptr not part of current TD ep_index 2 comp_code 13" that appear spuriously (or pretty often) when using a r8152 USB3 ethernet adapter with integrated hub. ASM1042 reports as a 0.96 controller, but appears to behave more like 1.0 Inspired by this email thread: https://markmail.org/thread/7vzqbe7t6du6qsw3 Cc: stable@xxxxxxxxxxxxxxx Signed-off-by: Jens Glathe <jens.glathe@xxxxxxxxxxxxxxxxxxxxxx> Signed-off-by: Mathias Nyman <mathias.nyman@xxxxxxxxxxxxxxx> Link: https://lore.kernel.org/r/20221024142720.4122053-2-mathias.nyman@xxxxxxxxx Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- drivers/usb/host/xhci-pci.c | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) --- a/drivers/usb/host/xhci-pci.c +++ b/drivers/usb/host/xhci-pci.c @@ -307,8 +307,14 @@ static void xhci_pci_quirks(struct devic } if (pdev->vendor == PCI_VENDOR_ID_ASMEDIA && - pdev->device == PCI_DEVICE_ID_ASMEDIA_1042_XHCI) + pdev->device == PCI_DEVICE_ID_ASMEDIA_1042_XHCI) { + /* + * try to tame the ASMedia 1042 controller which reports 0.96 + * but appears to behave more like 1.0 + */ + xhci->quirks |= XHCI_SPURIOUS_SUCCESS; xhci->quirks |= XHCI_BROKEN_STREAMS; + } if (pdev->vendor == PCI_VENDOR_ID_ASMEDIA && pdev->device == PCI_DEVICE_ID_ASMEDIA_1042A_XHCI) { xhci->quirks |= XHCI_TRUST_TX_LENGTH;
