USB Touchscreen monitor does not wake up system

[lalliss]

I am running Windows 7 Embedded and have a USB touchscreen monitor attached. I am running DisplayLink driver 7.7.60366.0 and TouchBase UPDD driver 5.0.2.0. I have set my device settings so the monitor can wake up the system and have disabled the USB Selective Suspend. I cannot get touchscreen action to wake up the computer from Standby. Note that the BIOS setting of the computer does not have any ACPI Power settings.
Is this a driver issue? Is this a BIOS/computer issue?
Thanks for any help.

This sounds like a problem between the touch screen driver and the system. DisplayLink are not connected to the touch screen device - it just looks like another device on the USB bus.
