What is the USB2.0-CRW device?

The CRW stands for Card Reader Writer and the device is a plug-in SD card reader/writer that has a USB 2.0 plug.

You may have one of these built into your PC as well which runs from this driver – attached directly to the motherboard without a plug.

Without the correct USB2.0-CRW driver present on your Windows operating system you will find that programs can’t communicate with the device.

You can download a new copy of the Realtek driver to fix the issue and gain back the ability to read SD cards again.

SD cards are small readable/writable storage media that look like larger sim cards that you find in your mobile phone.

You can use these SD cards to move files from one computer to another or a mobile device if it has a slot for the right size.

Who is Realtek?

In the late 1980s, the Realtek company was formed in China and went on to focus on developing chipsets for devices.

The company control a large share of the network card market as well as the basic audio card one too.

Nowadays the company pushes over $2b in sales worldwide and continues to innovate within the semiconductor market.

What is a driver?

A driver is essentially a collection of files that your Windows operating system uses in order to understand how hardware works.

When you connect a new device through USB for example Windows will quickly try to establish what it is.

Sometimes Windows will be able to recognize right away what it is and how it can interact with it, allowing software (such as programs and video games) to access its features.

Often you may find that a new device simply isn’t recognized straight away and so you need to find the correct “drivers” to make the link.

You can download these as an installable .exe file that has everything in it ready-to-go, you just double click and follow the instructions on the screen.
