I have a Dell XPS M1530 laptop. Recently, I’ve changed the settings of my Windows Vista in order to Windows 7. At the beginning everything was perfect, my USB mouse worked properly for the days. But the entire USB ports stopped working as soon as I input a memory stick. These nevertheless produce energy; however the Windows does not identify any kind of USB device in any way right now. Do you have some answer for this?
