Changes

USB devices which are connected are shown with a ''vendor:product'' value pair. Devices with ''0000:0000'' represent USB ports where no device is connected or a device is connected but currently powered off. A list of device ID strings is contained in the ''/usr/share/hwdata/usb.ids'' file). If no matching ID is found in the file this field is left blank. This file is constantly updated so it may be worth downloading the latest release from [http://www.linux-usb.org/usb.ids http://www.linux-usb.org/usb.ids].
