[Bug 1825736] Re: Mouse scroll wheel barely works after suspend
This is sporadically reproducible for me. It's probably a hardware quirk. I have Ubuntu 20.04 with Linux 5.4.0-37-generic. I'm using a "Microsoft Mobile Mouse 4000" which presents itself as 045e:07b2 "Microsoft Corp. 2.4GHz Transceiver v8.0 used by mouse Wireless Desktop 900". The issue only occurs when the transceiver is plugged into a desktop USB hub (MBHUB-43ST presenting as VIA Labs 2109:2813). When it is working, inspecting the event stream with cat /sys/kernel/debug/hid/.../events while slowly scrolling gives a series of events of size 3: report (size 10) (numbered) = 1a 00 00 00 00 00 03 00 00 00 Button.0001 = 0 Button.0002 = 0 Button.0003 = 0 Button.0004 = 0 Button.0005 = 0 GenericDesktop.X = 0 GenericDesktop.Y = 0 GenericDesktop.Wheel = 3 Consumer.HorizontalWheel = 0 Fast scrolling gives events that are some multiple of 3. After suspend/resume, the events have a size of 1: report (size 10) (numbered) = 1a 00 00 00 00 00 01 00 00 00 Button.0001 = 0 Button.0002 = 0 Button.0003 = 0 Button.0004 = 0 Button.0005 = 0 GenericDesktop.X = 0 GenericDesktop.Y = 0 GenericDesktop.Wheel = 1 Consumer.HorizontalWheel = 0 My reading of the source implies that the kernel is not scaling these events, the numbers are coming straight from the hardware. The power light on the desktop hub briefly goes off as the laptop enters suspend. This doesn't always happen but seems to be correlated with the mouse breaking. Removing and re-adding the usbhid kernel module does fix it, but I suspect that's because the device is reset rather than because of any state in the kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1825736 Title: Mouse scroll wheel barely works after suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1825736/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I've now tested the Microsoft mouse on my desktop computer and the scroll wheel works find after a suspend / resume, so this looks to be a clash with the hardware in the laptop - a Lenovo G510. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1825736 Title: Mouse scroll wheel barely works after suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1825736/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Updating to 19.10 hasn't fixed the problem, but I have just replaced my mouse and found the issue is no longer there with the new one. The original was a Microsoft Wireless Mobile Mouse 1000 (045e:0745 Microsoft Corp. Nano Transceiver v1.0 for Bluetooth) and the new one is a Logitech M220 (046d:c534 Logitech, Inc. Unifying Receiver). Not a fix, but a work around perhaps and extra info for any debugging. I still have the Microsoft one to test any fixes posted here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1825736 Title: Mouse scroll wheel barely works after suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1825736/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1825736] Re: Mouse scroll wheel barely works after suspend
I did not have this problem prior to upgrading to 19.04. The upgrade process was an upgrade from 18.04 to 18.10 with an immediate upgrade to 19.04 (after a clean reboot), so there was no usage of 18.10 as a desktop environment to compare with. The 18.04 install was kept up to date. I have tested using the installed linux-image-4.18.0-17-generic kernel and found that there are no problems. During the test process I have noted that there are no problems if the suspend is initiated manually using the top right 'menu' to suspend instead of shutdown or reboot. There is a problem, however, if the suspend is initiated by simply closing the laptop. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1825736 Title: Mouse scroll wheel barely works after suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1825736/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Is this a regression? Does this issue happen to previous kernel releases? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1825736 Title: Mouse scroll wheel barely works after suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1825736/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
