About
USB Mass Storage Support
This
document provides important information about USB Mass
Storage Support 1.3.5.
USB
includes the notion of Class drivers, a set of software
components generally delivered by Operating System vendors
that are able to communicate with not just one, but
many different USB devices of a particular kind. This
enables any number of compliant devices to be plugged
in and start working immediately without the need to
install additional software. Several Class Drivers are
already included in Mac OS for its computers with USB,
including a hub class driver and a composite class driver.
Over time, Apple expects to offer new and updated Class
drivers for USB. The Mass Storage Support software represents
one of these class drivers and is intended to support
devices that meet the USB Mass Storage Class specification.
This software consists of the two system extensions
USB Mass Storage Extension and USB Mass Storage Support.
IMPORTANT!
Not all devices meet the independently defined USB class
specification, and so, require their own unique software
to operate. Follow the vendor's directions for installing
software to support their device. Use this software
when the vendor recommends it or no other software is
available. It is okay for both this software and a vendor's
own software to be installed on the same system at the
same time. When both are installed at the same time,
the vendor's software will normally take precedence
over the USB Mass Storage Support extensions.
Requirements
Mass Storage Support 1.3.5 requires Mac OS 8.6. You
do not need to install this software if you have installed
Mac OS 9.

If
the message "The software needed to use the USB
device 'name of the device' can not be found" appears

you are using is not supported by the USB Mass Storage

When

close all windows and quit all running applications
that are stored on the device and drag the device's
icon onto trash to dismount it from the Desktop prior
to unplugging the device from the USB port or Hub.
IMPORTANT
Do not disconnect a mass storage device from the USB
port while copying files to or from the device or while
files or applications stored on the device are in use.
DOING SO MAY RESULT IN LOSS OF DATA.
