Public bug reported: [Impact] Some USB devices aren't working if they are plugged under system sleep.
[Fix] Consider xHCI PORTSC CAS bit over other conditions. [Test] Plug or re-plug USB devices during system sleep. USB devices always work after system resume. [Regression Potential] There could be devices that depends on the old (but wrong) behavior. However it's really unlikely and it's against xHCI spec, we can deal with those quirky devices if any. ** Affects: hwe-next Importance: Undecided Status: New ** Affects: linux (Ubuntu) Importance: High Status: Confirmed ** Affects: linux-oem-5.6 (Ubuntu) Importance: Undecided Status: Won't Fix ** Affects: linux (Ubuntu Focal) Importance: Undecided Status: Won't Fix ** Affects: linux-oem-5.6 (Ubuntu Focal) Importance: High Status: Confirmed ** Tags: oem-priority originate-from-1889734 somerville ** Also affects: linux-oem-5.6 (Ubuntu) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: linux-oem-5.6 (Ubuntu Focal) Importance: Undecided Status: New ** Changed in: linux-oem-5.6 (Ubuntu) Status: New => Won't Fix ** Changed in: linux (Ubuntu Focal) Status: New => Won't Fix ** Changed in: linux-oem-5.6 (Ubuntu Focal) Status: New => Confirmed ** Changed in: linux (Ubuntu) Status: New => Confirmed ** Changed in: linux-oem-5.6 (Ubuntu Focal) Importance: Undecided => High ** Changed in: linux (Ubuntu) Importance: Undecided => High ** Tags added: oem-priority originate-from-1889734 somerville -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1892678 Title: Fix non-working USB devices plugged during system sleep To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1892678/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
