+ | ====== 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. | ||
