I have a Logitech USB headset H540 that my MBP wont recognise. I have plugged it in,opened the system preferences and clicked both the input and the output but the headset does not even show up. I have unplugged it rebooted the computer, and tried all sorts of options.
MacBook Pro, iOS 7.1.2
What does Logitech say about this? It's is their hardware so they should have a solution. It almost definitely has nothing to do with iTunes itself (the forum on which you posted). Did you read the installation instructions? Some devices may requires specific drivers for which there may not be one for Macs, or certain output settings in your system preferences panels which you will have to peruse if they are not specifically outlined in your user manual.
Can I conect a Logitech USB headset H540 to a MBP?
