I find that the usb library has a lot of flaws. For example, it doesn't support python3. It also crashes frequently and requires a restart. USB is a protocol that allows data to be transferred between two interconnected devices, typically a computer and a peripheral device such as a printer or cellphone. USB has been an essential part of modern computing for over twenty years now, but it may not be long before we see its last days because USB is outdated technology and will soon be replaced by faster alternatives like thunderbolt 3. In this post I will explain what you can do with your usb library version 03.02. 07. First, if you are attempting to make a new USB connection with your computer you will first need to install the usb library. To do this, execute the command: sudo apt-get install libusb-1.0-0 and it should install for you. If there is another version of the library you will need to replace libusb-1.0-0 by whatever version of libusb is installed on your computer. Once this is done, we can begin making a new connection. To do this we first need to turn on our device and then plug it into the computer with a usb cable (the cable that it came with). Then we will need to make a call to the usb library and tell it that we want to create a new connection. The code for this is: import usb After we have connected, we need to read and write data to and from our device. To do this, we'll need the following: import usb The data is placed in a buffer with up to 7 bytes which can be accessed with pointers. The USB specification allows you to use any number of buffers but only one at a time. When making a connection, such as charging or data transfer, you can add more than one buffer in any order. It is important to note that the USB specification allows for devices with up to 16 endpoints. USB Hubs are only allowed one endpoint and hubs are not allowed to chain off of each other. This means that you can use no more than seven buffers in total, regardless of the number of endpoints that your device might have. The code for this is: import usb Note: I am using linux but it should work with Windows as well.
