 Posted: Wed Oct 23, 2019 12:25 pm Post subject: Disable USB port ? |
 |
|
Got a new mouse, and it has a very bright light coming out of it, mostly through scroll wheel, it makes problems during a night when I go to sleep.
Now, I know I can cover it with something or plug it off, or open it and do something with it etc.
But I'm wondering is there a way to disable USB port via some terminal command, piece of software or something like that, because I would prefer that option first.
I tried to google it, there was one option with powertop, that didn't work, then few commands via terminal, that didn't work as well, mostly because the posts were old and it was for older kernels.
So, can it be done ? |

| Code: | dmesg
...
[ 4963.102582] input: Logitech USB Laser Mouse as /devices/pci0000:00/0000:00:14.0/usb1/1-13/1-13:1.0/0003:046D:C062.0005/input/input17
|
the thing to get is that the mouse is input17 (for now)
off: echo remove > /sys/class/input/input17/event0/uevent
on: echo add > /sys/class/input/input17/event0/uevent
ps: i don't have a fancy light to see if it power it off for real, but at least, the mouse stop working in the UI |

Thanks for trying! |

well, i'm not in mood for disabling my whole usb port holding the mouse, but if you're in, maybe disable the usb port the mouse is attach to would do
you can get it with udevadm info /sys/class/input/input17
ps: of course you better make sure your keyboard isn't attach to that port too, else, you will have a little problem trying to send the add event next  |

I'm in the mood
I don't get it how to disable the port though, here's the output :

You can tell the kernel to put it in powersaving mode automatically after a timeout, which should kill the LED until you wake it up with a click.
Here's a config file I use for mine:
| /etc/udev/rules.d/local-usb.rules: |
ACTION!="add|change", GOTO="local_usb_end"
SUBSYSTEM!="usb", GOTO="local_usb_end"
# keyboard
ATTR{idVendor}=="045e", ATTR{idProduct}=="00db", ATTR{power/control}="auto", ATTR{power/autosuspend}="300"
# mice
ATTR{idVendor}=="045e", ATTR{idProduct}=="0039", ATTR{power/control}="auto", ATTR{power/autosuspend}="900"
ATTR{idVendor}=="045e", ATTR{idProduct}=="076c", ATTR{power/control}="auto", ATTR{power/autosuspend}="900"
# tablet
ATTR{idVendor}=="172f", ATTR{idProduct}=="0031", ATTR{power/control}="auto" # default timeout of 5 is fine
LABEL="local_usb_end"

Doesn't work, after I made that file I did '/etc/init.d/udev reload' , hope that was enough.
btw I changed timeouts to 5, just to test it out.
Is idProduct relevant maybe or something else in that config that I should perhaps change ?
edit:
I changed idVendor to 0000 and idProduct to 0538, but still no luck |

/sys/class/pci_bus/0000:00/device/00:010000.2/usb1/
(but your path have another bus 0000:01:00.0 in between so i'm less sure about the path, seek usb1 name to find the right path, you have the product file to see if its the controller and the uevent file there to try disable it)
| Code: | pwd
/sys/class/pci_bus/0000:00/device/0000:00:14.0/usb1
cat product

Well, I get what you're saying and what needs to be done, but having a hard time finding that path.
There are many combinations and seems like I have to manually go through each in order to find the right one.
Can't really deal with that at the moment so I'll try it when I can. |

| Your mouse also needs to be powersaving-capable. Chances are they skipped that part, because they couldn't even be bothered to get a real vendor ID. |

When I say it doesn't work I mean the light is still on but the mouse is disabled.
It's like doing it the other way krinn suggested.
I mean here's the log , it gets disabled, it gets enabled again on move/click.

That's why I think that disabling the port power is the way to go.
Telling the kernel that specific usb port doesn't exist, if possible.

A lot of computers cannot disable the power on USB ports while the computer is on.
A lot of mice do not know how to deal with power save.
Chances are, removing/masking the LED and/or replacing the sensor illumination LED with an infrared one is all you can do.

Yeah, well I kinda like the light when I'm not sleeping, was hoping that maybe there's a way.
Maybe I'll find it, not really in a rush, will not give up, for now covering the mouse with dark cloth works fine. |
