Description Rick Richard 2012-10-29 08:10:01 UTC
A change, apparently in later FBSD 8.x and in FBSD 9.x, causes usbus[0-n] devices to appear as network devices.  They do not show up in ifconfig -a but the do show up in netstat -i.

This causes a slowdown and errors at startup when both ifconfig_DEFAULT="DHCP" and synchronous_dhclient="YES" are set in rc.conf:

usbus0: not found
exiting.
Starting Network: usbus0.
usbus1: not found
exiting.
Starting Network: usbus1.

etc.

This has been mentioned in various places:

http://freebsd.1045724.n5.nabble.com/Prevent-starting-network-on-usbus-td5142292.html

etc.

How-To-Repeat: edit /etc/rc.conf and add
ifconfig_DEFAULT="DHCP"
synchronous_dhclient="YES"

restart and observe errors at startup or manually produce the problem by executing
/etc/rc.d/netif start usbus0
