Computer not waking with wireless USB devices

[cheezmunky]

I have a Toshiba P875-S7200, running Win7 Home Premium 64 with a Logitech K800 wireless keyboard and Logitech Performance MX wireless mouse operating through the same Logitech unifying USB device. The keyboard's power button works to put the laptop to sleep, but it will not wake it back up. The mouse will not wake the computer either. The power button on the laptop does wake the computer, as intended. I've researched the problem, tried everything I've come across so far, and nothing seems to let me wake the notebook from external USB devices. So far I have tried the following:



- I have checked to be sure that wake from keyboard is enabled in the BIOS.

- Under the device manager I've gone through the properties for two 'Generic USB Hubs' and two 'USB Root Hubs' and unchecked the option to allow the computer to turn off the device in power management. None of the other USB devices have the Power Management option.

- I have checked the option to allow the device to wake the computer for both the HID keyboard device and the Logitech HID-compliant unifying keyboard

- I have checked the option to allow the device to wake the computer for both the HID-compliant mouse and the Logitech HID-compliant unifying mouse



Is there something I am missing? Thanks for any help.

Check out advanced power options in control panel, there are a couple of options relating to USB devices and sleep modes that might help with your problem.
