I have a weird issue, I have a laptop acer aspire and after plug-in or out its power cord, the cursor doesn't work with the external usb mouse (it still work with the touchpad). If I plug-out and in again the mouse in the same usb slot, the cursor doesn't work either. I must plug it out, and plug it in in another USB slot to get back the mouse cursor.

That append each time the power is plugged in or out. Another way to get back the mouse cursor is to click with the mouse and to immediately move the mouse. But as soon I don't the mouse 1 or 2 seconds, the cursor doesn't move and I must click again.

Hi Dominique let me ask you two questions:

Are these unpowered ports? I ask because my laptop has two USB ports. One is designed to maintain power even in battery mode. The other will go into a low power state automatically as soon as I run off of battery. This appears to be built into the system. In my case simply reinserting the mouse works.
Are you running laptop-mode? If you are and if that kicks on when the power is changed it is possible that that is set to power down your USB. I had a similar problem on a prior version of it (that may be connected with my prior question) that has now disappeared. In effect laptop-mode can power down some parts of the system. It is possible that yours is triggering a module that limits usb.

Now I have another issue. This morning, after resuming, the keyboard and the mouse cursor was dead in X. Both the touchpad and the external mouse was dead. That imply it was not even possible to shift to a primary console via Ctrl-Alt-Fn or the quit menu. The only working things was the mouse buttons and the kernel magic keys.

That imply I reverted the change in runtime-pm.conf and I am back to case 1.

Hello,

I do not use laptop-mode but what I understand of the variable AUTOSUSPEND_RUNTIME_DEVID_BLACKLIST is that it blacklist devices from autosuspend according with their hexadecimal ID numbers xxxx:xxxx like the ones you get when you execute the command lspci -nn and lsusb. Use this variable with kernel modules names values to blacklist from autosuspend devices look without effect to me.

What can be done to verify if the source of your problem come from laptop-mode, is to stop it and than run X. You will see if your problem occur again or not. This should help.

The usbcore module have the parameter autosuspend who can be set to -1 to tell the module to not autosuspend

Interesting Logicien, now that I look at it you are right I have the value in the wrong location. I am surprised that it still seemed to work.

Thanks to a typo, I managed to get it to work. I wrote the following script, /etc/pm/sleep.d/00i8042 :
