This bug was fixed in the package tcpdump - 4.0.0-6ubuntu4

---------------
tcpdump (4.0.0-6ubuntu4) maverick; urgency=low

  * debian/usr.sbin.tcpdump:
    - allow device probing (LP: #585150)
    - allow 'w' access to /dev/bus/usb/**/[0-9]*, needed for proper USB
      probing with libpcap 1.1 and higher
