jedishrfu said:The man page for lsusb provides the necessary info ie what files to read:
http://linuxcommand.org/man_pages/lsusb8.html
Notice the /proc/bus/usb directory and the file /usr/share/usb.ids
No, the system() function returns an int, typically a status code that is returned by whatever system command was called.Stephen Tashi said:In C there is a command "system(...)" isn't there? it returns information in a string, so it is awkward to use.
In order to access the USB devices in C++ on Ubuntu OS, you can use the libusb library. This library provides a set of functions that allow you to interact with USB devices, including reading the list of connected devices.
The list of USB devices in C++ on Ubuntu OS is typically represented as an array of structures. Each structure contains information about a specific USB device, such as the device's vendor and product ID, and the device's name and serial number.
To iterate through the list of USB devices in C++ on Ubuntu OS, you can use a for loop or a while loop. In each iteration, you can access the information about a specific device by using the index of the array or by using a pointer to the current structure.
Yes, you can filter the list of USB devices in C++ on Ubuntu OS based on certain criteria, such as the device's vendor or product ID. This can be done by using the appropriate functions provided by the libusb library, such as libusb_get_device_list() and libusb_get_device_descriptor().
In order to handle errors when reading the list of USB devices in C++ on Ubuntu OS, you can use the error handling functions provided by the libusb library. These functions allow you to check for and handle any errors that may occur during the interaction with USB devices, ensuring that your code runs smoothly and without any unexpected crashes.
