A Logitech Gaming Mouse G400 keeps disconnecting randomly. In the event reported below, it disconnected after 5.9 hours.
I have already:
disassembled the mouse and pulled the cord a few centimeters into the mouse
blacklisted the mouse from usb autosuspending:
# in /etc/udev/rules.d/50-usb_power_save.rules # blacklist for usb autosuspend ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="05c6", ATTR{idProduct}=="9205", GOTO="power_usb_rules_end" ACTION=="add", SUBSYSTEM=="usb", TEST=="power/control", ATTR{power/control}="auto" LABEL="power_usb_rules_end"set the Kernel boot parameters:
acpi=offandusbcore.autosuspend=-1

Thicker part of the cable located in the bend has indeed deteriorated, but pulling the cord a few centimeters into the mouse seems to have fixed it; if I disconnect from the USB port and reconnect, the mouse work again. Moreover, even if there is still some problem with the cable, it seems from the dmesg report above that it goes back quickly to its place, and a reconnection is tried.
Why isn't the reconnection reported by dmesg successful, and what can be done about it?
