    Action: "remove",
    KObj:   "/devices/pci0000:00/0000:00:14.0/usb1/1-1",
    Env:    {"PRODUCT":"58f/6387/10b", "TYPE":"0/0/0", "DEVNUM":"005", "SEQNUM":"2549", "ACTION":"remove", "DEVPATH":"/devices/pci0000:00/0000:00:14.0/usb1/1-1", "SUBSYSTEM":"usb", "MAJOR":"189", "MINOR":"4", "DEVNAME":"bus/usb/001/005", "DEVTYPE":"usb_device", "BUSNUM":"001"},
}
