Public bug reported: [Impact] Hotplug a USB3 device to HP dock can go undetected.
[Fix] Add a delay for USB3 hub resume routine so the link has enough time to transit to U0. [Test] After the patch is applied, the dock can always detect USB3 devices. [Where problems could occur] A non-noticeable delay was added, so no basically no impact. ** Affects: linux (Ubuntu) Importance: Medium Status: Confirmed ** Affects: linux-oem-5.14 (Ubuntu) Importance: Undecided Status: Invalid ** Affects: linux (Ubuntu Focal) Importance: Undecided Status: Won't Fix ** Affects: linux-oem-5.14 (Ubuntu Focal) Importance: Medium Status: Confirmed ** Affects: linux (Ubuntu Jammy) Importance: Medium Status: Confirmed ** Affects: linux-oem-5.14 (Ubuntu Jammy) Importance: Undecided Status: Invalid ** Also affects: linux-oem-5.14 (Ubuntu) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Jammy) Importance: Undecided Status: New ** Also affects: linux-oem-5.14 (Ubuntu Jammy) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: linux-oem-5.14 (Ubuntu Focal) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Focal) Status: New => Won't Fix ** Changed in: linux (Ubuntu Jammy) Status: New => Confirmed ** Changed in: linux (Ubuntu Jammy) Importance: Undecided => Medium ** Changed in: linux-oem-5.14 (Ubuntu Jammy) Status: New => Invalid ** Changed in: linux-oem-5.14 (Ubuntu Focal) Status: New => Confirmed ** Changed in: linux-oem-5.14 (Ubuntu Focal) Importance: Undecided => Medium -- 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/1955443 Title: Fix USB3 detection on HP dock Status in linux package in Ubuntu: Confirmed Status in linux-oem-5.14 package in Ubuntu: Invalid Status in linux source package in Focal: Won't Fix Status in linux-oem-5.14 source package in Focal: Confirmed Status in linux source package in Jammy: Confirmed Status in linux-oem-5.14 source package in Jammy: Invalid Bug description: [Impact] Hotplug a USB3 device to HP dock can go undetected.
