For these devices, you have to manually load a device driver. And here's the key mistake a lot of folks make. They assume that just because you can plug a thumb drive into the system, and Windows will automatically load the drivers for us, that you should be able to plug any plug and play device

into the system and rely on Windows to load the appropriate drivers and that just isn't true. The best practice for loading a driver for one of these types of devices is to actually install a driver first, before you connect the device to the system. That way, when we plug the device in, Windows will then probe the device and recognize right away that it already has the appropriate device driver to support that device. Now, is it all lost if you don't do that? If you plug it in first? No. More than likely what will happen is the device will show up as either unrecognized or Microsoft will load some generic driver to provide a minimal level of support for the device. And then you're going to have to go into Device Driver and then manually select the driver you want to use. Let's not make that mistake on this system. I have a USB plug and play, video-capture board here that I want to connect to the system, and I happen to know that the appropriate drivers are not available in the Microsoft driver store. So, the first thing I'm going to do is install the appropriate device drivers on this system. Okay, so this device came with its own device driver disk. I'm going to click on this option and I'm going to run the installer off of the installation disk to load the appropriate drivers. And we'll click the option to install the driver. Okay, the driver installation routine is complete. I'll exit out of the installation interface.And now I'm going to connect the device to an open USB port on the system. When I do, because Windows already has the device driver installed, it should be able to query the device, see what kind of device it is, recognize that it already has the appropriate device driver and load it. So you can see that it detected that this was a video-capture board. And the device has been successfully added to the system. Now, as you go through this process, understand that there are two different places where Microsoft stores device drivers. There is a driver store that's includedwithin your Windows installation. They're stored locally. There's a whole bunch more that are stored out on the Internet. So the first thing that Windows is going to do when it detects a device like this, is it will query the local driver store to see if a device driver exists there. If not, then it will go out onto the Internet. Go to Microsoft site and see if Windows Update has the necessary driver for the piece of hardware, and if it does, it will download and install it. Understand that process takes a while to complete.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
