V-USB on an ATmega328! - V-USB and HID Explained

Sometimes, we only have access to microcontrollers without all of the peripherals that we need. Several cases like in the AVR line of microcontrollers involving USB support. Luckily there is a library called V-USB that allows us to bit-bang USB support into our projects.

Add USB To Your Electronics Projects! - The USB Protocol Explained

USB is both the simplest and most complex interface to use. It is simple to plug in and let the computer handle. It is complex to create and run a microcontroller with it.

How to Use a Computer, Part 1: USB Devices

You’ve been brought up around smartphones and tablets all your life, and now you’re in a situation where you need to use a Windows PC. No problem! With a little practise, you’ll find that PCs are easier to work with and can even do more than a mobile device. Incidentally, “PC” in this context stands for “personal computer”. It’s a holdover from the IBM PC in the ‘80s. These are the absolute bare-bones basics of computer literacy and can apply to MacOS and Linux distros as well, but Windows is the most common OS (operating system) that you’ll find on a day-to-day basis.

So, let’s get on with it then!

First, let’s cover the biggest bit of computers: USB devices. The USB standard is even used to a certain degree on smart devices, but they get taken to an absurdist extreme on the PC. Literally everything of practical use these days connects to the PC through a flat USB port. That flat bit that goes into your device charger can also be plugged into a PC for file transfer between your device and your PC. The technical name for this is “USB type A”. At the other end of the cord is either a USB type C connector (if you use an Android device) or an Apple Lightning connector (iOS).

If you have an Android device, try plugging your USB-A connector into your PC instead of the power outlet and see what happens (though, you might have to tell your device that you’re trying to connect to a PC; a prompt should come up on your homescreen).

An aside, what does USB stand for? Universal serial bus. You don’t need to remember that for any reason, though.

The biggest thing we use USB for is file storage. Those little USB sticks they sell at Office Depot expand the storage capability of your PC’s hard disk (main storage unit) by anywhere from 8 to 512 Gigabytes. These are called “flash drives” because they use a memory chip called “flash memory” (SD cards do the same thing). They can also be called “thumb drives” because they’re the size of your thumb. Or “USB drives” if you’re an ageing computer science professor.

We also use USB ports for keyboards, mice, MIDI controllers, detachable webcams, drawing tablets, or really anything at all.

To use a flash drive, all you have to do is plug it into a free USB port on your PC. Older PCs have most of their ports in the back, but newer ones have at least 2 ports in the front for easier access. Typically, you won’t need to do any more than this, because Windows is smart enough to know what a flash drive looks like and how it works.

In fact, a lot of USB devices don’t need to be installed or formatted; especially the basic ones, like keyboards, mice, and USB hard disks. Specialised devices, like MIDI controllers and webcams, may need to install device drivers, which usually come either on an optical disc packed in with the device or from the manufacturer’s website.

That’s about all she wrote for USB devices. Next time, we’ll cover optical discs and why you need a disc drive.

Plugging in USB (type A) devices became so much easier when I realized that most cables and plugs have a logo, bump, divot, or something pointing to or on the side which is 'up' (up in this case being the part with the gap in the device you're plugging in and the plastic barrier in the receiving plug).

I still love USB type C for the convenience of not having to worry about up and down but this knowledge about the type A plugs has saved me so much trouble x3

Beware that Hackers Using Malicious USB Devices to Deliver Multiple Malware

Recently, Mandiant Managed Defense discovered cyber espionage activity that focuses on the Philippines and mainly uses USB drives as an initial infection vector. This operation, which Mandiant tracks as ‘UNC4191’, has a connection to China. The report states that operations of UNC4191 have had an impact on a variety of public and private sector organizations, primarily in Southeast Asia and…
