Back in the Windows world there was a Device Manager control panel that would list all the devices that were connected to your computer.

There was even an option to show "hidden devices", basically a list of items like thumb-drives, SD cards, etc. that were once connected to your PC.

I'm just curious if something like this exists in OSX? Is there a list of devices that are connected or ever were connected?

Search for System Information in Lion or later (or System Profiler in Snow Leopard and earlier versions of Mac OS) in Spotlight (press and Space).

The program is in /Applications/Utilities and is the tool to see the connected USB devices and other hardware details. It is quite simliar to Device Manager on Windows.

Alternatively you can access it via the Apple Menu

-> About This Mac -> More Info... -> System Report...

System Information

The System Information can save system profiler information to a file, so you could review an older snapshot to see what was connected once, but the Mac OS doesn't record all the devices connected - just the ones actually connected when you run the tool and it scans the current items on the device tree.

+1, BUT: System Profiler does NOT offer you any option to change device settings. – Max Ried Apr 29 '12 at 10:37
remark: this instructions are correct for osx 10.7. On 10.6 and before its called: System Profiler – Chrisii Apr 29 '12 at 11:48
Thanks! And it's good to know that OSX doesn't record all the connected devices. That was one feature that annoyed me in Windows because I would become so OCD that I would periodically go in and delete/cleanup the unused invisible items! – kleniq May 19 '12 at 10:31
the profiler just only shows the report you can't configure or reinstall your device or drivers – Amare May 4 '15 at 5:36
remark: in Mavericks (10.9) and above, the More Info... button is now labelled System Report.... – Ben C. R. Leggiero Nov 19 '15 at 22:41
