I'm having the exactly same problem as rea30. I tried to solve it as nuhi advised but there was a problem. I'm a real newbie with this stuff so bear with me: First I extracted the usbehci.sys with 'expand' in command promt but then modifyPE couldn't "open the file". Step-by-step tuts or any help at all in fact would be appreciated. This problem really has frustrated me for a while now.
