How to configure a usb device

[Sun Zongjun-E5739C]

Hi, all

I want to use a usb network interface on FreeBSD6.1 as well as I use it
on linux. When insert the USB into Linux box and run ifconfig command,
it will report that a usb0(1, 2) can be used now. But when I insert the
same USB device into the FreeBSD box, FreeBSD only report that some USB
device has been detected, there is nothing on the screen when I run
ifconfig command.


I am a newbie to FreeBSD. How can I know whether my FreeBSD can support
this devices like Linux?

Thanks for your help very much
