--- Comment #1 from Carlo Wood (carlo@alinoe.com) ---
I have the same problem.
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!
