reading USB port in Linux

I am writing a program to read data from a Bluetooth USB dongle. I am using Linux, so I suspect there may be a POSIX library to read from it, or perhaps there is a predefined file descriptor for each USB drive. How do I read a stream of data from a USB port in C?

Solution

  • The most common way of interacting with random USB device is libusb. This provides low-level access to the device, so if you want something more complex (for example, if it's an actual USB drive with a filesystem on it), you might want to use some existing driver for the device rather than trying to interact with it directly.
