HID_n_Seek is a software which can browse all the HID device connected with the Mac. HID devices are keyboard, mouse, joystick and gamepad. In function, the HID_n_Seek is almost the same to the HID Explorer which was released by Apple Inc. in the sourcecode. I rewrite it with Cocoa. Therefore, HID_n_Seek is a Cocoa native software. When running, uses might find a button "Element Test". It means that we can test our HID button or other elements by pressing the button. Please use Pop-Up button to choose the device or the element in Pop-Up List.
