I'm plugging in a USB device which should be a USB/serial adapter. In addition to it not seeming to work, plugging and unplugging it produces absolutely no output in Console.app or /var/log/system.log. Is there any lower level place I can look to see what's happening when I plug it in?
You need to install the usbutils commands via
macport (sorry, I don't use
sudo port install usbutils
then, for a first check, try the following command:
You should see a list of your USB devices. It might be hard for you to identify your device. A good way to filter all your devices is to remove every of them except your USB/serial adapter.
lsusb returns nothing. Your device is dead.
If my memory is good, the name of an USB-serial adapter printed ends by:
USB-Serial (UART) IC
