The problem is no new driver is being installed in my laptop when attached. Usually when a new pendrive is connected, the driver of that pendrive is installed in the laptop (it shows a "installing driver" window then). But now no new driver is being installed successfully in my laptop when a new device is attached. So the pendrive is not detected naturally. Also, today I bought a MBlaze device and connected it. The same problem happened this time too and a message came saying I have to install the drivers manually. So how can I solve this problem?
My OS is Windows 7 and the same MBlaze device installed successfully on my bother's Windows 7 laptop without downloading the drivers from the manufacturer's site.
