Steps to wake Windows 7 PC?

I cannot get USB-UIRT to take my cpu out of sleep mode in Windows 7.
I have the lrnhelper utility, programmed the buttons I want to use. The USB-UIRT box lights up whenever I press a button and the PC is sleeping, but nothing happens. The keyboard and mouse will still take the PC out of sleep mode. I tried using old vista drivers posted in another thread - they didn't help.
