Explicitly UP and DOWN the usbus interfaces (IFT_USB) when it's attached
or detached. Normally it should be changed through user land ioctl(2)
system calls but it looks there's no apps for USB and no need.
With this patch, libpcap would detect the usbus interfaces correctly and
tcpdump(1) could dump the USB packets into PCAP format with -w option.
However it couldn't print the output to console because there's no
printer-routine at tcpdump(1).
