Hi, I'm using a Texas Instruments PCIe XHCI USB card on x86-64 machine running Linux v4.11-rc6 with Ubuntu. I can manage to get the XHCI controller in a unresponsive state with the following message on a device disconnect [ 242.817353] usb 9-3: USB disconnect, device number 9 [ 247.919845] xhci_hcd 0000:03:00.0: xHCI host not responding to stop endpoint command. [ 247.919898] xhci_hcd 0000:03:00.0: Assuming host is dying, halting host. [ 247.947777] xhci_hcd 0000:03:00.0: Host halt failed, -110 [ 247.947781] xhci_hcd 0000:03:00.0: Non-responsive xHCI host is not halting.

Same issue is seen on older kernels as well. I've tried v4.1 and v4.4. lspci -nn shows 03:00.0 USB controller [0c03]: Texas Instruments TUSB73x0 SuperSpeed USB 3.0 xHCI Host Controller [104c:8241] (rev 02) Apparently this controller uses Synopsis XHCI core which is XHCI v0.96 compliant SNPS_ID: 0x5533171a John, Is there any quirk required for this controller that we're missing? cheers, -roger -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
