Finally...Fix it. I checked that all port setting and bios were ok. Put userport.exe, ntportio in same folder as div5 and userport.sys in Windows/system32/driver. Start userport and give at least 10sec (you can close it but dont press "stop") then open Div5 and everything ok..... If this doesnt work then you have a faulty dongle, and how to make sure, try it in another computer.
Thanks to Bungle
FYI I have Windows XP SP2. |
