Hi, I have been there before that USB-Devices and inlayed discs in my MacBook Pro was shared in MacOS and Windows7 at the same time. After a reinstallation of Parallels and Windows in case of a HD-crash that doesn't work anymore. I have to click on parallels-menu > devices > USB and so on... to get access to the devices either on MacOS or on Windows. Is this a problem of configuration? Thanks! Andreas
