I am having a Acer 9410Z laptop and it has Windows Vista Home Premium on it. The laptop works fine, but I am not able to figure what issue lies with usb drive. When I connect a usb device, it is not detected. Basically in Windows XP it is detected as plug and play device. It looks Vista is not having any driver for the same. There are not indication on the screen about the usb device. It is a bit complicated for me to figure out how this is going to work.
