Public bug reported: == SRU Justification == [Impact] Some QCA ROME bluetooth devices does not work after runtime suspend/resume after SRU LP: #1734020.
[Fix] The commit let btusb reset at second time it resume, i.e. btusb_open(). The btusb stops working because the reset happens *after* btusb_open(). The reset should be done at hub port initialization, before btusb_probe(). Revert the bad commit and use the reset-resume quirk in USB core stack. [Test] Cherry-picked the commit into Artful/OEM kernel and the issue is fixed. [Regression Potential] Low. This is limited to QCA Rome, also verified by the original quirk author. ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1741206 Title: QCA Rome bluetooth failed to work after applying reset-resume quirk To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1741206/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
