* usb: add quirks for Lenovo OneLink+ DockJean-Francois Le Fillatre2022-09-301-0/+4

Some downstream ports (both internal to the built-in audio and network controllers, and external to USB sockets) may no longer be functional. The exact list of disabled ports (if any) changes from wakeup to wakeup. Ports remain in that state until the dock is power-cycled, or until the laptop is rebooted. Wakeup sources connected to the hubs (keyboard, WoL on the integrated gigabit controller) will wake the system up from suspend, but they may no longer work after wakeup (and in that case will no longer work as wakeup source in a subsequent suspend-wakeup cycle). This issue appears in the logs with messages such as: usb 1-6.1-port4: cannot disable (err = -71) usb 1-6-port2: cannot disable (err = -71) usb 1-6.1: clear tt 1 (80c0) error -71 usb 1-6-port4: cannot disable (err = -71) usb 1-6.4: PM: dpm_run_callback(): usb_dev_resume+0x0/0x10 [usbcore] returns -71 usb 1-6.4: PM: failed to resume async: error -71 usb 1-7: reset full-speed USB device number 5 using xhci_hcd usb 1-6.1-port1: cannot reset (err = -71) usb 1-6.1-port1: cannot reset (err = -71) usb 1-6.1-port1: cannot reset (err = -71) usb 1-6.1-port1: cannot reset (err = -71) usb 1-6.1-port1: cannot reset (err = -71) usb 1-6.1-port1: Cannot enable. Maybe the USB cable is bad? usb 1-6.1-port1: cannot disable (err = -71) usb 1-6.1-port1: cannot reset (err = -71) usb 1-6.1-port1: cannot reset (err = -71) usb 1-6.1-port1: cannot reset (err = -71) usb 1-6.1-port1: cannot reset (err = -71) usb 1-6.1-port1: cannot reset (err = -71) usb 1-6.1-port1: Cannot enable. Maybe the USB cable is bad? usb 1-6.1-port1: cannot disable (err = -71) 2) Some USB devices cannot be enumerated properly. So far I have only seen the issue with USB 3.0 devices. The same devices work without problem directly connected to the host system, to other systems or to other hubs (even when those hubs are connected to the OneLink+ dock). One very reliable reproducer is this USB 3.0 HDD enclosure: 152d:9561 JMicron Technology Corp. / JMicron USA Technology Corp. Mobius I have seen it happen sporadically with other USB 3.0 enclosures, with controllers from different manufacturers, all self-powered. Typical messages in the logs: xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command usb 2-1.4: device not accepting address 6, error -62 xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command usb 2-1.4: device not accepting address 7, error -62 usb 2-1-port4: attempt power cycle xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command usb 2-1.4: device not accepting address 8, error -62 xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command usb 2-1.4: device not accepting address 9, error -62 usb 2-1-port4: unable to enumerate USB device Through trial and error, I found that the USB_QUIRK_RESET_RESUME solved the second issue. Further testing then uncovered the first issue. Test results are summarized in this table: ======================================================================================= Settings USB2 hotplug USB3 hotplug State after waking up --------------------------------------------------------------------------------------- power/control=auto works fails broken usbcore.autosuspend=-1 works works broken OR power/control=on power/control=auto works (1) works (1) works and USB_QUIRK_RESET_RESUME power/control=on works works works and USB_QUIRK_RESET_RESUME HUB_QUIRK_DISABLE_AUTOSUSPEND works works works and USB_QUIRK_RESET_RESUME ======================================================================================= In those results, the power/control settings are applied to both hubs, both on the USB2 and USB3 side, before each test. From those results, USB_QUIRK_RESET_RESUME is required to reset the hubs properly after a suspend-wakeup cycle, and the hubs must not autosuspend to work around the USB3 issue. A secondary effect of USB_QUIRK_RESET_RESUME is to prevent the hubs' upstream links from suspending (the downstream ports can still suspend). This secondary effect is used in results (1). It is enough to solve the USB3 problem. Setting USB_QUIRK_RESET_RESUME on those hubs is the smallest patch that solves both issues. Prior to creating this patch, I have used the USB_QUIRK_RESET_RESUME via the kernel command line for over a year without noticing any side effect. Thanks to Oliver Neukum @Suse for explanations of the operations of USB_QUIRK_RESET_RESUME, and requesting more testing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | As there will be more USB4 devices that support NVM firmware upgrade from various vendors, it makes sense to split out the Intel specific NVM image handling from the generic code.

Fix this by moving the check before reset label since this check only be valid if the data after bulk_in_buffer[HEADER] has concrete data.

Fix this by removing the zero value checking.

| | | | | | | | | | | | | | | | | | | | | | In the probe path, dev_err() can be replaced with dev_err_probe() which will check if error code is -EPROBE_DEFER and prints the error name. It also sets the defer probe reason which can be checked later through debugfs. It's more simple in error path.
