The Valve Index HMD uses the xhci_hmd driver for a USB 3 connection. The culprit shows usually in dmesg as: [77865.729313] xhci_hcd 0000:08:00.0: xHCI host not responding to stop endpoint command. [77865.729989] xhci_hcd 0000:08:00.0: xHCI host controller not responding, assume dead [77865.729995] xhci_hcd 0000:08:00.0: HC died; cleaning up After which obviously no new connections can be made anymore. I compiled vanilla 5.6.0-rc7 with >grep XHCI .config CONFIG_USB_XHCI_HCD=m CONFIG_USB_XHCI_DBGCAP=y CONFIG_USB_XHCI_PCI=m # CONFIG_USB_XHCI_PLATFORM is not set reloading the xhci_pci module restores the controller. If someone has patches to try out then I can apply them and test it out. If any other info is needed please ask! -- You are receiving this mail because: You are watching the assignee of the bug.
