To do so first do a "cat /proc/acpi/wakeup". and then write corresponding device name (the first column) to that file (under root) For example, mine /proc/acpi/wakeup: maxim@MAIN:~$ cat /proc/acpi/wakeup Device S-state Status Sysfs node SLPB S4 *enabled P32 S4 enabled pci:0000:00:1e.0 UAR1 S4 enabled pnp:00:0a ILAN S4 enabled pci:0000:00:19.0 PEGP S4 enabled pci:0000:00:01.0 PEX0 S4 enabled pci:0000:00:1c.0 PEX1 S4 enabled pci:0000:00:1c.1 PEX2 S4 enabled pci:0000:00:1c.2 PEX3 S4 enabled pci:0000:00:1c.3 PEX4 S4 enabled pci:0000:00:1c.4 PEX5 S4 enabled UHC1 S3 enabled pci:0000:00:1d.0 UHC2 S3 enabled pci:0000:00:1d.1 UHC3 S3 enabled pci:0000:00:1d.2 UHC4 S3 enabled EHCI S3 enabled pci:0000:00:1d.7 EHC2 S3 enabled pci:0000:00:1a.7 UH42 S3 enabled pci:0000:00:1a.0 UHC5 S3 enabled pci:0000:00:1a.1 AZAL S3 enabled pci:0000:00:1b.0 maxim@MAIN:~$ the UHC1-5, EHCI and EHC2 are the usb1.0 resume devices (ports) so I can do echo "UHC1" > /proc/acpi/wakeup echo "UHC2" > /proc/acpi/wakeup .... And then check whenever the "status" column" shows "enabled" Note: some resume devices are connected together: For example doing 'echo "ILAN" > /proc/acpi/wakeup' enables the LAN , EHCI , AZAL. So my script that enables all wakeup devices is: #! /bin/bash echo "UHC1" > /proc/acpi/wakeup # ICH8 UHCI1 echo "UHC2" > /proc/acpi/wakeup # ICH8 UHCI2 echo "UHC3" > /proc/acpi/wakeup # ICH8 UHCI3 echo "UHC4" > /proc/acpi/wakeup # ICH8 UHCI4 echo "UHC5" > /proc/acpi/wakeup # ICH8 UHCI5 echo "ILAN" > /proc/acpi/wakeup # ICH8 internal (lan/HDA/EHCI) echo "P32" > /proc/acpi/wakeup # ICH8 external (PCI/PCI express) echo "UAR1" > /proc/acpi/wakeup # SUPERIO (UART/Sleep button) And last thing, writing to /proc/acpi/wakeup a device name that is already enabled, disables it, so if I for example run the above script twice (with wakeup devices disabled), all wakeup devices will be disabled again.
