How to turn off USB Auto Suspend

I used powertop which suggested turning on the usb suspend feature. I told powertop to turn it on. Now I can't turn it off! it's really annoying because I use a usb mouse, and it take a few seconds before it will work now every time I stop using it. How can I disable this feature?

Re: How to turn off USB Auto Suspend

Look for these files:

/etc/modprobe.conf
/etc/modprobe.d/modprobe.conf
/etc/modprobe.d/options

And check if they have "options usbcore autosuspend=1" inside.

Re: How to turn off USB Auto Suspend

*BUMP*
Not working for me. I'm unable to disable USB autosuspend. Any device I plug, while on battery power, does not work and after plugging kworker starts to eat my CPU.
Waiting for about ten minutes my laptop finally recognizes the device.

I'm on 2.6.39-ARCH x86_64

EDIT: Sometimes waiting for devices to be recognized doesn't work. kworker just keeps on running. I wonder if this is a kernel bug on some hardware?

Re: How to turn off USB Auto Suspend

Have you tried looking in /etc/laptop-mode/conf.d/usb-autosuspend.conf for config options?

Re: How to turn off USB Auto Suspend

Try putting this line:

CONTROL_USB_AUTOSUSPEND=0

in /etc/laptop-mode/conf.d/usb-autosuspend.conf

Re: How to turn off USB Auto Suspend

I disabling it on modprobe and laptop-mode might work.
I got this solved a long time ago. I also added some new parameters to kernel.

Now I don't have auto-suspend on no more. kworker problem also vanished.
Thanks.

How did you disable autosuspend in modprobe? By setting usbcore.autosuspend to "0"? What other parameters were configure to solve this problem?

I am experiencing same issue. In battery mode, the USB device is not usable if it is not attached on boot. Disabling USB autosuspend in laotop-mode conf does not help.
