[Bug 1856161] Re: Thunderbolt dock fails to connect USB devices
After an update to 5.3.0-26-generic (and then some time passed), got a connection fail when unsuspending.

The `logitech-hidpp-device` is the Logitech unified receiver I have connected to the dock. It always generates lots of error messages like this, even when connected directly to the computer's built-in USB port.

With the `dyndbg` flag, I can't seem to reproduce the problem: I tried to connect and disconnect the cable a few times as well as rebooting (which was almost 100% guaranteed to cause this issue). I attached logs of the successful thunderbolt connection while running and a boot log with the dock already connected. There are things there that seemed to me like error messages that might be interesting regardless? I'll continue using the `dyndbg` flag and will report later this week if the problem has been reproduced (I connect the dock a could of times a day, usually when the computer is already on, but sometimes when it is suspended or off), or whether enabling the debug flag is a workaround :-p ** Attachment added: "lp1856161-dyndbg-logs.tar.gz" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1856161/+attachment/5316687/+files/lp1856161-dyndbg-logs.tar.gz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1856161 Title: Thunderbolt dock fails to connect USB devices To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1856161/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1856161] Re: Thunderbolt dock fails to connect USB devices
Since I started getting the bug 1766076 xhci failure, this problem has become more acute as the automatic workaround described in 1766076 no longer works - when resetting the xhci bus, the bus fails to be set up properly due to this issue and I'm left with a non-functioning system. See attached log for when trying to reset the xhci bus while all devices are connected to the dock. Currently my recovery procedure is either: - reset the bus again (manually) and pray for it to work (it does every 5-6 times) - or manually disconnect the USB chain (I've moved it to the front port so its more accessible); reset the bus; wait for everything to settle; count to 5; reconnect the USB chain. The counting part is important as if I attach the chain too early after the last xhci message in dmesg, it fails to setup with the same error as if it was connected during the reset. ** Attachment added: "reset-xhci-failure.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1856161/+attachment/5316520/+files/reset-xhci-failure.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1856161 Title: Thunderbolt dock fails to connect USB devices To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1856161/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Tries booting with the chain disconnected from the dock, and as expected - the system boots correctly with the dock attached and built-in USB devices present, after which plugging the USB cable in works well.

[Bug 1856161] Re: Thunderbolt dock fails to connect USB devices
apport information ** Tags added: apport-collected ** Description changed: Using Ubuntu eoan fully updated with kernel 5.3.0-24-generic on a Dell Precision 5520. When connecting a Dell Thunderbolt dock TB16, the USB bus connects very slowly (15~20 seconds) and sometimes does not connect at all and a failure is reported in dmesg: [ 117.834621] xhci_hcd :0e:00.0: xHCI host not responding to stop endpoint command. [ 117.850643] xhci_hcd :0e:00.0: Host halt failed, -110 [ 117.850644] xhci_hcd :0e:00.0: xHCI host controller not responding, assume dead [ 117.850679] xhci_hcd :0e:00.0: HC died; cleaning up [ 117.850717] xhci_hcd :0e:00.0: Timeout while waiting for configure endpoint command The slow connection seems to be a feature of the current updated firmware - the computer was not used for ~6 months due to a battery issue that was fixed, and after fixing the battery a new firmware was installed using the MS-Windows Dell software update utility. Both on Linux and MS-Windows the process of connecting the Thunderbolt dock completes after a much longer time than it used to in the beginning of the year. On the face of it it seems that the longer init process now hits timeouts in the xhci_hcd driver and depending on the exact timing often causes the xhci_hcd to give up and drop the USB Thunderbolt bus. This happens about 50% of the time, when connecting the Dock when the system is running, and a bit less when the system is booted or resumed from sleep when the dock is already connected. fwupdmgr report: -8<- Precision M5520 Thunderbolt Controller DeviceId: 51d36e5f8f25bea1d8707a72ab7b9386a98527ee Guid: c5364422-2ec3-5092-b30e-03bdb1a53e4a Summary: Unmatched performance for high-speed I/O Plugin: thunderbolt Flags:internal|updatable|require-ac|registered Vendor: Dell VendorId: TBT:0x00D4 Version: 26.01 VersionFormat:pair Icon: computer Created: 2019-12-12 Dell Thunderbolt Cable DeviceId: aa4dfab63945b6e8ad913550d241978e3562f8bf ParentDeviceId: 84edf044a6b53037732cfc7591b65a8d36384cc9 Guid: b4fd3cdf-4e3a-5090-a583-45367cfd6421 Plugin: thunderbolt Flags:updatable|require-ac|registered Vendor: Dell VendorId: TBT:0x00D4 Version: 16.00 VersionFormat:pair Icon: audio-card Created: 2019-12-12 Dell Thunderbolt Dock DeviceId: 64575ad9f31dbe3959942f4b2275c1c4d0ac2ac5 ParentDeviceId: 84edf044a6b53037732cfc7591b65a8d36384cc9 Guid: 76cc74d4-f062-5b93-a11c-8d2a58a25848 Plugin: thunderbolt Flags:updatable|require-ac|registered Vendor: Dell VendorId: TBT:0x00D4 Version: 16.00 VersionFormat:pair Icon: audio-card Created: 2019-12-12 Precision 5520 System Firmware DeviceId: f4b6e3af5b4bf8ad1f2ed2922b76df457271 Guid: 34578c72-11dc-4378-bc7f-b643866f598c Plugin: uefi Flags: internal|updatable|require-ac|supported|registered|needs-reboot Checksum: SHA1(f5dfd993019fd1ab6bdcb718f13a27d6f77a9a90) Checksum: SHA256(a35b224919bebade597cfbce372a235c96cb4c5489738804aec117ed92e85717) Version: 0.1.16.0 VersionLowest:0.1.16.0 VersionFormat:quad Icon: computer Created: 2019-12-12 UpdateState: success Synaptics VMM3320 inside Dell WD15/TB16/TB18 wired Dock DeviceId: 7b3cbc344094ace839263dd4711c84ea99bb6dc3 ParentDeviceId: 84edf044a6b53037732cfc7591b65a8d36384cc9 Guid: 152a9833-41e6-5c21-9dde-0ff8984f3e20 Guid: 0a52c8c7-26d5-59a0-ae44-6b00e276d775 Guid: 51000744-2de6-5a52-8a86-d5f69fd73d34 Summary: Multi-Stream Transport Device Plugin: synapticsmst Flags:updatable|registered Vendor: Synaptics Version: 3.10.002 VersionFormat:triplet Icon: computer Created: 2019-12-12 Synaptics VMM3330 inside Dell WD15/TB16/TB18 wired Dock DeviceId: d83854e8c81f5d47b0b99c8a3b42ae5127c75eb8 ParentDeviceId: 84edf044a6b53037732cfc7591b65a8d36384cc9 Guid: c0f73159-4fc0-509b-80f8-5f871f3751a8 Guid: be025b25-ca5c-546c-97c6-ee2160ba489d Guid: 190e8d7c-6bcf-5fab-94e7-4f8739eb90aa Summary:
