I can remove keyboard and mouse, plug them into another USB-port and with some luck use them again. Plug them back in the original port and they are disabled again. Hi Can you share with us some dmesg after such input outage? You can clearly see those USB disconnects. Here's an idea: How about a simple app that allows you to install fixes from the forum? Create both files below, then: systemctl enable suspendfix. Congrats Nice workaround. Thanks Guy. You can also try to upgrade your kernel to latest - this solved many issues i got with my setups.
An official flavour of the Ubuntu family. If you suspend your computer and then resume it again, you may find that your internet connection, mouse, or some other device does not work properly. This could be because the driver for the device does not properly support suspend. This is a problem with the driver and not the device itself. If the device has a power switch, try turning it off and then on again. In most cases, the device will start working again. If it connects via a USB cable or similar, unplug the device and then plug it in again and see if it works.
If you cannot turn off or unplug the device, or if this does not work, you may need to restart your computer for the device to start working again.

My computer is suspended and is not resuming. My wireless connection or other hardware does not work when I wake up my computer.
This guide will explain how to configure your USB input devices to be able to wake-up your suspended computer. As a result, you will be able to wake-up your Ubuntu computer with :. It has been written on a Ubuntu Precise As USB power management has changed drastically in kernel 3. As this is heavily dependant on the hardware, you may have to go thru your BIOS options to be sure that it is enabled.
Not all USB devices are able to handle suspend mode, while they get a low power supply. If your only goal is to get your USB devices handling your computer resume, you don't need to read this part, go straight to the next paragraph. To be able to resume your computer with this USB device, you will need to have a wake-up power supply on every active device of the chain.
In this way, even with the computer suspended, a minimum power will be supplied to the devices, so that they can send the wake-up signal. By simply writing enabled in that file, you are configuring it to get the wakeup power supply during suspended mode. So to enable a USB device to be used to resume your computer, you simply need to enable every active device on the connexion chain from the PCI bus till the device itself. The udev rule will take care of the power configuration of the connexion chain from the device till the PCI bus.
This script will be called by the udev rules we will create later in this article. This script is mainly a loop running thru the device connexion chain, starting from the device and going upward till the PCI root. With latest udev version, the new script is taken into account as soon as it is saved.
The window will list all the USB devices available on your computer, excluding hubs. Improve this question.
