Root Help usb debugging no screen

Hello I just replaced the digitizer on my HTC Wildfire S CDMA. list of problems short i need to recalibrate the screen using a program with a gold card. the problem is as I am attempting to set all this up my device does not read on my pc. I dowloaded the sync tool but that does not render without enabling the USB debug. Unfortunately i cannot access anything on my phone so i am curious is there is a program in which i can enable USB debugging without entering my phone screen. Longshot but can anyone out there help me if they have been through a similiar situation or knows how i can set this up. PLEASE AND THANK YOU

 

what is eclipse? im attempting to use it to develop and debug directly from pc. any help from users of this program?
