path_to_inst output for usb storage device

Hello,

I have a sun blade 100 with solaris 10 and am perplexed by the instances of devices that I see when I attach a usb flash stick to one of the ports in the back of the chassis.

Here is what I see for USB storage in /etc/path_to_inst:

"/pci@1f,0/usb@c,3/storage@3" 0 "scsa2usb"
"/pci@1f,0/usb@c,3/storage@3/disk@0,0" 0 "sd"
"/pci@1f,0/usb@c,3/storage@1" 1 "scsa2usb"
"/pci@1f,0/usb@c,3/storage@1/disk@0,0" 2 "sd"

It seems to me there is only usb device other than keyboard and mouse attached, can someone explain this output?

Thanks

NAME
lsusb - list USB devices SYNOPSIS
lsusb [ options ] DESCRIPTION
lsusb is a utility for displaying information about USB buses in the system and the devices connected to them. OPTIONS
-v, --verbose Tells lsusb to be verbose and display detailed information about the devices shown. This includes configuration descriptors for the device's current speed. Class descriptors will be shown, when available, for USB device classes including hub, audio, HID, communi- cations, and chipcard. -s [[bus]:][devnum] Show only devices in specified bus and/or devnum. Both ID's are given in decimal and may be omitted. -d [vendor]:[product] Show only devices with the specified vendor and product ID. Both ID's are given in hexadecimal. -D device Do not scan the /dev/bus/usb directory, instead display only information about the device whose device file is given. The device file should be something like /dev/bus/usb/001/001. This option displays detailed information like the v option; you must be root to do this. -t Tells lsusb to dump the physical USB device hierarchy as a tree. This overrides the v option. -V, --version Print version information on standard output, then exit successfully. RETURN VALUE
If the specified device is not found, a non-zero exit code is returned. FILES
/usr/share/usb.ids A list of all known USB ID's (vendors, products, classes, subclasses and protocols). SEE ALSO
