From 6e014b000a525f396b9c3565826c63642e052df7 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Mon, 25 Aug 2014 12:21:56 +0200 Subject: [PATCH] xhci: Disable streams on Via XHCI with device-id 0x3432 This is a bit bigger hammer then I would like to use for this, but for now it will have to make do. I'm working on getting my hands on one of these so that I can try to get streams to work (with a quirk flag if necessary) and then we can re-enable them. For now this at least makes uas capable disk enclosures work again by forcing fallback to the usb-storage driver. https://bugzilla.kernel.org/show_bug.cgi?id=79511 Bugzilla: 1132666 Upstream-status: Sent for 3.17 and Cc'd stable Cc: stable@vger.kernel.org # 3.15 Signed-off-by: Hans de Goede --- drivers/usb/host/xhci-pci.c | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/drivers/usb/host/xhci-pci.c b/drivers/usb/host/xhci-pci.c index 687d36608155..d973682f72ce 100644 --- a/drivers/usb/host/xhci-pci.c +++ b/drivers/usb/host/xhci-pci.c @@ -151,6 +151,11 @@ static void xhci_pci_quirks(struct device *dev, struct xhci_hcd *xhci) if (pdev->vendor == PCI_VENDOR_ID_VIA) xhci->quirks |= XHCI_RESET_ON_RESUME; + /* See https://bugzilla.kernel.org/show_bug.cgi?id=79511 */ + if (pdev->vendor == PCI_VENDOR_ID_VIA && + pdev->device == 0x3432) + xhci->quirks |= XHCI_BROKEN_STREAMS; + if (xhci->quirks & XHCI_RESET_ON_RESUME) xhci_dbg_trace(xhci, trace_xhci_dbg_quirks, "QUIRK: Resetting on resume"); -- 1.9.3
