Three days ago, I downloaded a NEAT freebie: USBMonitor. It shows you what's plugged in (and working) every time you change something. There is also a similar thing that costs US $9, "Peripheral Vision," and it monitors USB, Firewire, etc. So fat, I have only run the freebie: README - USB Monitor version 1.1.1 What is USB Monitor? Have you ever plugged in a USB device only to be underwhelmed by the reaction of OS X? It can be very confusing when the system seems to pay no attention to what's just been plugged in - did it even notice? We often brought up Apple System Profiler to check if the device got registered. USB Monitor eliminates the guess work. It pops up a little window and provides the name of the device that's just been plugged in (or unplugged). The window follows the visual style of the transparent windows for volume and eject. Note we have another product called "Peripheral Vision" that extends this functionality to FireWire, Bluetooth and Network Link Status. It also adds audio alerts. What's New in 1.1.1 * Fixed a memory leak. Requirements Mac OS X 10.1 and above. Installation Just drag the USB Monitor icon to the Utilities directory of your choice or run it in place from the disk image. If you have already installed USB Monitor you will need to quit it before copying the new version. To quit the running app use the "Process Viewer" utility. Using USB Monitor Once started USB Monitor pops up a status window showing the currently connected devices. No icon is added to the dock as this program is intended to run in the background and not be interacted with by the user. The best way to configure USB Monitor is to add it to your Login Items in your Login Preferences. That way it will always be running when you're logged in. (If you have a need to stop the USB Monitor app use the Process Viewer utility and stop it from there.) Known Issues None at this time. Bugs, Issues etc. None.
