Public bug reported:
since upgrading from 18.04 to 20.04 i experience interruptions of my usb
keyboard every few minutes. during these events either keys are ignored
or get repeated until i press the same key again.
in dmesg it is shown like this:
[206129.443725] usb 2-1.4: reset full-speed USB device number 7 using ehci-pci
[206131.063578] usb 2-1.4: reset full-speed USB device number 7 using ehci-pci
[206132.719719] usb 2-1.4: reset full-speed USB device number 7 using ehci-pci
[206134.143584] usb 2-1.4: reset full-speed USB device number 7 using ehci-pci
[206135.923480] usb 2-1.4: reset full-speed USB device number 7 using ehci-pci
i tried plugging it to different usb ports. it happens on any ports but
i noticed it happens way more frequently on the ports on the backside of
the PC than on the front side (they happen to be different usb busses).
i also did upgrade the BIOS to the latest version, but that did not
change the behavior at all.
