Detecting A USB Storage Device From A Script

I need a way to reliably detect a USB storage device from a bash script. I know how to use 'lsusb' to list the USB devices - but then how can I match a device listed in 'lsusb' output to an actual disk device? Is there some way to map one to the other? Any help appreciated.

ehci

EHCI(4)                                                    BSD Kernel Interfaces Manual                                                    EHCI(4)

NAME

     ehci -- USB Enhanced Host Controller driver

SYNOPSIS

     device ehci

DESCRIPTION

     The ehci driver provides support for the USB Enhanced Host Controller Interface, which is used by USB 2.0 controllers.

     EHCI controllers are peculiar in that they can only handle the USB 2.0 protocol.  This means that they normally have one or more companion
     controllers (i.e., ohci(4) or uhci(4)) handling USB 1.x devices.  Consequently each USB connector is electrically connected to two USB con-
     trollers.  The handling of this is totally automatic, but can be noticed since USB 1.x and USB 2.0 devices plugged in to the same connector
     appear to connect to different USB busses.

SEE ALSO

     ohci(4), uhci(4), usb(4)

HISTORY

     The ehci device driver first appeared in FreeBSD 5.1.

BUGS

     The driver is not finished and is quite buggy.

     There is currently no support for isochronous transfers.

BSD                                                               March 20, 2005                                                               BSD
