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?

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.

OK, given the answer above: the PS3 controller is, almost certainly, a HID device. You pair with it like you do any other Bluetooth HID device. It will appear as a joystick (or mouse, or keyboard, as appropriate) automatically once paired, with no software required on your part. This site seems to have a guide, though obviously I haven't tested it: http://www.ydl.net/support/solutions/ydl_6.x/ps3_bluetooth_sixaxis.shtml
