| + | ====== USB Dead after Suspend in Ubuntu ====== | ||
| + | After susbending Ubuntu on my laptop, all the USB devices are dead. The fix is fairly simple. | ||
| + | |||
| + | Edit the /etc/default/acpi-support file. | ||
| + | |||
| + | cd /etc/default | ||
| + | sudo vim acpi-support | ||
| + | |||
| + | Change the modules line to the following: | ||
| + | |||
| + | MODULES="usbcore" | ||
| + | |||
| + | This will cause the USB modules to be disabled and sleep and re-enabled on wake. | ||
