Hey. I Got Windows 7 on my Boot Camp And i installed on it libusb. After i installed it it killed all my keyboard and mouse devices and now i can't connect anything and to move back to Mac OSX, I tried to connect many other keyboard and mouses and nothing worked. I've been wondering if there is anyway to move back to Mac OSX And to fix my devices on the Windows by pressing anything in the keyboard while restart or so. Does anyone have any ideas? Thank you very much. I'm very stuck right now.
