How to list devices connected to Mac's USB ports?

How do I list the devices connected to the mac and get their /dev/tty things in Objective C?

I would really love to do this for an application that I've been building for the past day or so.

I need to list the devices connected to the mac, and find one that will suit my criteria for this application. How do I find the devices, and list the开发者_JS百科ir /dev/tty's as NSStrings in a list?

Finding and Accessing Devices will get you additional information.

The header file Mounter.h

#include <sys/param.h>
#include <sys/ucred.h>
#include <sys/mount.h>
@interface Mounter : NSObject {

struct statfs *buf;
int i, count;
@private

}

-(void) getMountList;

@end

The implementation Mounter.m file:

#import "Mounter.h"


@implementation Mounter

-(void) getMountList {

  NSFileManager *fm = [NSFileManager defaultManager];
  count = getmntinfo(&buf, 0);
  for (i=0; i<count; i++)
  {

        NSString *path = [NSString stringWithUTF8String:buf[i].f_mntonname];

        NSLog(@"Drivers: %@", path);
  }
