Hi,

There are some USB drivers which run in userland that will not work until this 
library is complete. These are currently not part of the FreeBSD 
distribution. You find them in /usr/ports :

grep libusb /usr/ports/INDEX

The kernel USB drivers provided under /sys/dev/usb2 do not directly depend on 
any userland utilities, but rather indirectly through the TTY, KBD, NET ...

One exception is the USB mouse driver which depends on "moused", and currently 
have some warnings because moused tries to load the old ums module, which 
fails.
