There are two functions that perform USB port of our boxes and motherboards. On the other hand, there is an app for data on the ports that connect to our PC. But, on the other hand, there is also the function of to feed in these parts. For either of these two functions, the port needs to be able to provide the necessary power needed to process the fault. And with this, it is necessary to know what voltage is capable of supplying the USB for each of our machines.
By using a USB voltmeter
As the name implies, a USB voltmeter It is a tool that connects between the USB port and the device. In doing so, it is able to measure the car's power output from the USB port connected to it. This way, we'll know as soon as the port supplies the power that the device needs to operate.
There are many USB voltmeters types market From simplicity, it only shows voltage. Even more complete, like the one in the previous photo, which has the ability to display a lot of information, such as the amperage and power consuming this device.
By a third party system
There are applications that can give us more information about the USB functionality of our system. Very good USBDeview. This system will not show us the large amount of data in the USB ports used on our machines.
In order to use this program, the first thing we will do is go Nirsoft download page and download the program. It's a totally free program.
He file which we will download will be suppressed. When you open it, we will find many files, but the most useful one is the USBDeview, which has the USB symbol.
You don't have to double-click on that icon to start performing program
In doing so, what we will see is is ready of USB ports that are currently active. As well as the history of USB ports used recently in the system. And what kind app Used it.
The value data The system provides us can be difficult for any user. But the fact that we are so passionate about the program, in this lesson, is close to the right.
As you can see, there is a column showing the usage of USB devices which we connected at the time. Although there is still another way to access all this information. If we double-click on any connected app, the next window will open.
This window is related to USB pen drive which is connected to a PC. When looking at where the mouse point is located, the use of the app is obvious. A recurring item in the PC keyboard environment.
And in the case of mouse
That's why USBDeview lets us know that port USB works just fine. Since we knew the app usage, we didn't know this feature of the screen. Also, as you have seen in the previous pictures, each device uses a very different amount of power.
