2 Steps to Fix USB Composite Device Driver

 If you get an error after plug in a USB device into your computer such as USB mouse, you can fix it without easily without need to install any drivers.


 The error is due to missing USB.inf file in your system. The USB.inf and USB.pnf located at C:\Windows\inf folder.

What what we need to do now is:

1. Copy the USB.inf and USB.pnf from other computer. It is located a t C:\Windows\inf folder.
2. Now paste on your C:\Windows\inf folder.

alternatively you can copy the USB.inf from your own computer located at C:\Windows\System32\DriverStore\FileRepository\usb.inf

However the file name could be different such as

C:\Windows\System32\DriverStore\FileRepository\usb.inf_amd64_neutral_42d7284868af1f40

Fix "A CD/DVD drive device driver is missing" during Windows 7 Installation

One of the classic error I always get since windows 7 release is "A CD/DVD drive device driver is missing". If you have a driver floppy disk,CD,DVD or USB Flash Drive, please insert it now.

 Solution: Disable USB 3.0 on BIOS
-Enter BIOS and look for USB 3.0 setting.
-Select Disable or if disable option is not available select Auto.

IF you are using DVD to Install Windows 7
This error pop-out when you have faulty Windows 7 installation DVD. You need to create new Installation disk (Using new DVD). Faulty Windows 7 installation disk could be your DVD disk or DVD drive faulty. The best way is to create a bootable USB installation disk.

IF you can't disable USB 3.0
If your computer BIOS does not have an option to change the USB 3.0 setting, you need to integrate the USB 3.0 driver into your windows 7 installation disk. You can obtain USB 3.0 drivers from your computer manufacturer download page. The most common USB 3.0 port used on current computer and laptop is Intel USB 3.0 which you can download the driver software from Intel website.
