[Plextalk] connecting ptp1

Hello listers, on windows xp I manage to connect the pocket, then if I want to charch it on USB, I would simply virtually aject it and it will restart and charch. Now that I'm on windows7, its no longer the case. Nothing happens if I safely remove the device but leave it physically connected, it just stays in disk drive moad. Is there perhaps a setting in windows wich could affect this behaviour? Or is it no longer possible to charch the pocket in this mannor on a pc?
