I ordered a SanDisk 4.0 GB Cruzer Micro USB Flash Drive with my Vostro 400 computer running Windows Vista 32 bit Home Premium Edition. When I inserted the Flash Drive in the USB port Windows asked me to install the driver for the device. There was no software included with the Flash Drive. I checked the box requesting Windows to look for a driver through the Windows Update feature. It came back and said no driver could be found for this device. I then went to the manufacturer's website but they don't have a driver listed for this particular Flash Drive. I called Dell and all they could tell me is that Windows should have recognized the device automatically. Any suggestions on how I can get Windows to recognize this device. My brother has the same identical computer and Flash Drive and his installed without a problem
