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

UHMODEM(4)						   BSD Kernel Interfaces Manual 						UHMODEM(4)

NAME
uhmodem -- USB support for Huawei 3G wireless modem device SYNOPSIS
uhmodem* at uhub? ucom* at uhmodem? HARDWARE
The uhmodem driver supports the following adapters: Huawei E220 E-mobile D01HW E-mobile D02HW NTT DoCoMo a2502 DESCRIPTION
The uhmodem driver provides support for the Huawei 3G wireless modems and its variants. This type of device has multiple com ports. And some modems have own storage to contain its device driver (for Windows). The uhmodem driver can handle all of these functions on the device. When the device attached, it will attach multiple ucom devices. The former one is main com device to use communication with your network provider, and others are sub com devices to monitor the condition of data communication and/or network status. These com devices can be used simultaneously. The device is accessed through the ucom(4) driver which makes it behave like a tty(4). SEE ALSO
tty(4), ubsa(4), ucom(4), usb(4) HISTORY
The uhmodem driver first appeared in NetBSD 5.0. Separate from ubsa driver. BSD
