[Kernel-packages] [Bug 1766076] Re: USB over thunderbolt turns off every once in a while
#107 (sorry, my previous message was meant as an answer to #107 too!) Incidentally, linux-oem-5.10 does not fix this my issue (with a WB19TB dock). Does this kernel work well with the TB16? What are the relevant logs I should join to my bug report to linux- oem-5.10? Is dmesg output enough? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1766076 Title: USB over thunderbolt turns off every once in a while Status in Dell Sputnik: New Status in linux package in Ubuntu: Incomplete Bug description: I'm using a USB hub in the Dell TB16 (240W) connected to a Dell Precision 5520 using Thunderbolt 3.

[Kernel-packages] [Bug 1766076] Re: USB over thunderbolt turns off every once in a while
#106 The described symptoms are so specific that it would be a really surprising coincidence if my issue had a different cause with so identical symptoms. Are you sure this is really about the dock? What if it was actually about the thunderbolt controller on the motherboard instead? I assume most people who post here also have similar computers (being Dell consumers). Another argument supporting this theory: the system switches to the faulty mode after a suspend/resume of the computer. Nothing you do with just the dock triggers the faulty mode until you suspend/resume the computer and, after that, nothing you do with the dock (including powering it down and up again) will switch the system back to the non- faulty mode until the computer is powered down. Moreover the system switches to faulty mode as soon as a computer suspend/resume occurs, even if no thunderbolt dock was actually plugged in yet when the computer was suspended. Of course I don't know what are the results of the investigations so far, so I may be completely wrong. But then it would be very interesting to know the explanation. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1766076 Title: USB over thunderbolt turns off every once in a while Status in Dell Sputnik: New Status in linux package in Ubuntu: Incomplete Bug description: I'm using a USB hub in the Dell TB16 (240W) connected to a Dell Precision 5520 using Thunderbolt 3.

[Kernel-packages] [Bug 1766076] Re: USB over thunderbolt turns off every once in a while
I have a very similar issue with a WD19TB under Ubuntu 20.04 (Dell Latitude 5410) and desperately browsing the net, looking for solutions. Everything works fine until I resume from suspend. Then all USB devices connected to the dock start having failures (like missing key presses for the keyboard, mouse becoming sluggish until the device is disconnected, or sound becoming bad, also I suspect the ethernet port of the dock doesn't work well anymore). This is most likely *not* a thunderbolt authorization issue (I tried all the security modes: no security/user based/key based, all show the same behavior), which is a definite difference with many reports I found here and there (and makes it hard to find the same exact one as the one I have). The present issues description from the opener seems close enough, including dmesg output (although the opener had a Dell 16TB dock). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1766076 Title: USB over thunderbolt turns off every once in a while Status in Dell Sputnik: New Status in linux package in Ubuntu: Incomplete Bug description: I'm using a USB hub in the Dell TB16 (240W) connected to a Dell Precision 5520 using Thunderbolt 3.

Suspend still works fine if I boot with previous kernel (4.15.0-55-generic). Looking at the changelog, I suspect the following change to be the cause of this regression: >> - usb: xhci: Prevent bus suspend if a port connect change or polling state is detected Indeed, my dmesg is also spammed all the time with USB failures and I would not be surprised that this change disallows suspending just because something is happening on my USB bus.

[Kernel-packages] [Bug 1838514] [NEW] Suspend failure with kernel 4.15.0-56-generic
