MacOS: PowerPC running MacOS 8.6 or
better, and a USB port. Any Macintosh
computer with one or more USB ports
running Mac O/S 8.6 or later (the US-224
has not been tested with Mac O/S X as of
this writing. Please check the website for
updates).
Very early iMac computers may need one
(or more) firmware updates to use the US-
224. Which firmware update(s) is (are)
needed depends on which Mac O/S version
is installed in the early iMac. Apple provides
details in its Apple Support Article #58174.
PowerBook G3 Series (or later) with built in
USB (or using a 3rd party PCMCIA USB
Card) have been tested and work fine.
Additionally, older PowerMac computers
using 3rd party PCI-based USB cards also
have been tested and work fine. Any iMac,
G3 or G4 will work fine as well. A MacOS
version earlier than 8.6 will not implement
full USB support, and is not recommended.
Again, plenty of RAM and fast drives are
suggested.
3.2 Installation
Because the US-224 is a USB device,
connection is pretty straightforward. Simply
plug the USB cable into the US-224, and the
other end into your computer.
Make certain that your computer’s USB host
port is enabled. (Normally, most standard
PC BIOS settings default to enabled, but
make certain that it hasn’t been turned off in
the BIOS).
NOTE: Handle the enclosed CD-ROM with
care. If it becomes dirty or scratched, it will
be impossible for a computer to read it, and
the software cannot be installed. If the disc
becomes unreadable, a charge will be made
for its replacement.
Do not attempt to play the enclosed CD-
ROM using an audio CD player, as this may
cause damage to hearing, as well as to
speakers, etc.
Use only the enclosed USB cable to connect
the US-224 and the computer. Do not use
other types of cable for this purpose, as
some cables contain resistors. If you attempt
to use such a cable, the audio input and
output will not work properly, and the sound
level will be inaudible or very faint.
3.2.1 Windows
The US-224 drivers are available on the CD
as executable installers. You’ll find two
executable installer files on the disk, labeled
as:
“US224_Win98_Install_1_10.exe”
(for Windows 98 Second Edition and
Millennium Edition) and
“US224_Win2k_Install_1_10.exe”
(for Windows 2000 and Windows XP).
Note that we have also included the
individual driver files as a ZIP file, for users
wishing to install via Windows Hardware
Manager. However, we recommend using
the installers, as they will also locate and
uninstall any files pertaining to older
versions of the US-224 drivers.
To install under Win98SE or ME:
Note: The US-224 will run under Win98 SE
(Second Edition) or ME (Millennium Edition).
Due to its limited USB capabilities, First
Edition Win98 is not recommended.
Note: Run the Installer with US-224
turned OFF.
Double click on the executable file
“US224_Win98_Install_1_10.exe”. (The
blue US-224 icon). The installer will run.
Click the "Setup" button. The Welcome
dialog box will appear.
Click the "Next" button. The driver files will
be installed to your hard drive.
