Hello. After random period(5min-40min) mouse speed changed by itself. Pointer speed settings in control panel didnt changed, mouse dpi also didnt changed, but mouse pointer moves faster than it should be. After rebooting pc mouse speed revert back to normal but again after few random period mouse speed changed by itself. I tried to set all dpi profiles to same dpi(i use 400 dpi and 4th tick speed in mouse settings at control panel), delete all dpi profiles except one with 400dpi, disable dpi button, reconnect mouse to different usb ports, switch to windows 11(23h2), switch back to windows 10(22h2), enable/disable xhci hand-off, install windows10/11 in uefi and csm mode, enable/disable secure boot, reset bios settings, disable/enable c-state, disable/enable pss, disable/enable pbo, disable/enable core boost, change psu idle current to typical/low, set manual cpu clock to 3.5Ghz, set manual voltage for cpu/soc, disable xmp, set ram to default clock, manual set ram speed/voltage/timings, manual set infinity fab clock, change 3 new mouses, change mousepad, try other manipulation but it didnt help. Switch from windows to linux(i used xorg and xfce and gnome DE) and test my rig on archlinux, manajro, debian stable, debian testing, ubuntu and after random period(5min-40min) mouse speed changed by itself, mouse settings didnt changed in DE applet for mouse settings, output from xinput for my mouse didnt changed, but mouse pointer moves faster than it should be. After rebooting pc mouse speed revert back to normal but again after few random period mouse speed changed by itself. Switch from libinput drivers to evdev and switch back again to libinput, also test new mouses, use other manipulation but it didnt help. My mobo shipped with latest bios out of the box. I dont have any bsod on windows10/11 or bsod analogs on linux systems. RAM tested with memtest86, memtest86+, windows memory tester and no errors found. Tried to check and restore windows with sfc/dism/chkdsk but it didnt help. Install windows and linux on ssd, then install windows and linux on hdd, but it didnt help. Smart status of hard disks are ok and ssd are also new from the shop.

I am experienced pc user since 90's year.

 After almost 2 month of testing and trying to fix my issue i can clearly say that:

1)it can be bios firmware problem

2)maybe i got defective cpu out of the box

3)maybe i got defective mobo out of the box

4)maybe i got 3 different defective mouses out of the box

5)maybe i got combo with different combinations from 1) to 4)

Also i got the same issue on my old am3+ rig from 2013 year. So after to switching from old am3+ to new am4 rig i got the same problem. Is this only amd problem with usb devices? Am i the chosen one? Please, help me

many have this issue, did you find anything

i did many investigation on internet but i dont know how to fix this. Also i tried to RMA new rig but local shop service said that my rig working properly. Also i discovered:

1. mobo recognize two xmp profiles 3600mhz for 2x8GB xpg, while my memory has two xmp profiles(3200,3600)

2. when you disable/enable rebar and above 4g decoding and press save settings and reboot then bios firmware said that you have not made any changes. But after rebooting system at info programs(hwinfo, etc) said that rebar enabled.

3. when you start disable cpu cores(in random order) then system halt at boot with error "overclock failed". And you dont overclock anything.

4. when you lock cpu at fixed clock( i tried 4ghz and set multiplier for ccd) then after rebooting bios firmware show cpu clock 3.6Ghz instead of 4ghz)

5. There is a burning smell from some ports on the back panel of the motherboard (4 USB 2.0, HDMI, DVI, VGA). Connectors from devices enter one USB 2.0 port with effort, as if something is in the way inside the port.

6. Sometimes usb devices reconnecting, or not recognized after boot. And i cant reproduce it, it starts randomly and not often

7. Mouse movements feels differently if you connect mouse to usb 3.0 port(back panel) instead of usb 2.0. My latest mouse working as usb 1.1 device, keyb working as usb 1.1 or 1.0 (i dont remember, i used usb treeveiw program)

8. Also i found my old g203 prodigy mouse. This mouse working as usb 2.0 device. After 2-10 minutes g203 disconnected from usb 2.0 port and cursor dont move. But if you plug g203 to usb 3.0 port then mouse working but freezing for 1 sec after every 2-5 minutes. Maybe my g203 prodigy is too old and working incorrect. I cant find new g203 prodigy in local shop, so i dont know what other mouses now working as usb 2.0 device to buy for testing. Logitech downgrade sensor in g102 lightsync, so it can be working as usb 1.1 device.

9. If you use linux system in csm mode then you stuck at grub boot menu if you press any key on keyboard at this stage

I am sick and tired of it. I should have bought Intel instead of AMD then

You likely have another app that is setting the mouse speed when the app runs.  I had a problem with a Kensington Mouse app that would alter the mouse settings after Windows was up and running.  Look for any app that is running (use Task Manager to find them) and disable them one by one until you find the one doing the changes.

I tried mouses that dont have any software app. I tried mouses with software app, uninstall software app, no difference
