Wake from S3 - again!

[LeaUK]

I've enable USB wake in the BIOS, added USBBIOSx reg key and programmed the USB UIRT with wake up IR codes but it still fails to wake my PC

I notice the red RX LED flashes for a longer period when receiving the wake IR code, but it fails to wake.

Any tips much appreciated.

To prevent a negative end-user experience, Windows XP and Windows Server 2003 modify the power capabilities that are returned by the BIOS. Therefore, the system only supports wake by using the USB for the S1 system power state. If there is no USB device that is armed for wake from a system power state, the system enters the S3 system power state during standby. For systems that correctly support wake by use of the USB from the S3 system power state, this behavior can be modified by using the following registry entry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\usb
"USBBIOSx"=DWORD:00000000

My registry hive didn't have a usb key (a yellow folder) so I simply created a DWORD value under Services - WRONG

If you don't have a usb key, create one. Then place the USBBIOSx DWORD beneath.
