Problem with USB - solaris 10 on VMware

I am running solaris 10 on VMware and I do not know how to setup the USB drive. After refer to few doc from sun still unable to get what i should do.
Can someone help?

On VMware I have added a USB controller.

Oh yes, from prtconf and dmesg, it don't seem to reganize the usb controller. I believe I have to make the system to recognise the USB first.
# prtconf| grep USB
# prtconf| grep usb
# dmesg |grep usb
#

below are the vfstab config
# more vfstab
#device device mount FS fsck mount mount
#to mount to fsck point type pass at boot options
