So the only notification you'll get is when devfs creates a device. Since there is no predictable link between a USB device and a disk device, info from the USB stack would be less then usefull. You can check this by reading from /dev/devctrl (when devd is not running, since this device can only be opened by one program at a time) just after you plugged in the device. For my usb thumbdrive I get: cat /dev/devctl !system=DEVFS subsystem=CDEV type=CREATE cdev=pass2 !system=DEVFS subsystem=CDEV type=CREATE cdev=da0 !system=DEVFS subsystem=CDEV type=CREATE cdev=da0s1 !system=DEVFS subsystem=CDEV type=CREATE cdev=msdosfs/RFS1 While sysctl gives: dev.umass.0.%desc: vendor 0x3538 USB Mass Storage Device, class 0/0, rev 2.00/1.00, addr 2 dev.umass.0.%driver: umass dev.umass.0.%location: port=4 interface=0 dev.umass.0.%pnpinfo: vendor=0x3538 product=0x0042 devclass=0x00 devsubclass=0x00 release=0x0100 sernum="000000000004E1" intclass=0x08 intsubclass=0x06 dev.umass.0.%parent: uhub4 So for now, you'll have to match on the creation of da* devices, or labels if you use those.
