That was the first thing I tried. Didn't helped.

No libcap from ports installed. And both affected programs linked to
systemlibpcap:
hilko@falko:~> ldd /usr/sbin/tcpdump
/usr/sbin/tcpdump:
libpcap.so.7 =3D> /lib/libpcap.so.7 (0x28112000)

hilko@falko:~> ldd /usr/local/bin/scanlogd
/usr/local/bin/scanlogd:

Thats true, but that wasn't the case here. In my understanding it's
related to this from the 8.3-Releasenotes:
| The FreeBSD usb(4) subsystem now supports USB packet filter. This =
allows
| to capture packets which go through each USB host controller. The
| implementation is almost based on bpf(4) code. The userland program
| usbdump(8) has been added.[r221174]
After that 'netstat -i' shows usbus entries. And it seens the
contributed libcap doesn't know how to handle that.
