OHCI systems have no problems with
the US-122, occasionally some older
OHCI systems will exhibit problems. We
have found that, in the majority of these
rare cases, a PCI-based USB card utiliz-

Web site for updates), or Mac OS X

Very early iMac computers may need
one (or more) firmware updates to use
the US-122. Which firmware update(s)
is (are) needed depends on which Mac
OS version is installed in the early iMac.
Apple provides details in Apple Support
Article #58174.

Installation

Because the US-122 is a USB device,
connection is straightforward. Simply
plug the USB cable into the US-122, and
the other end into your computer. How-
ever, you should not connect the unit
before installing the drivers (see below).
Windows machines:
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).
Also make sure that virus protection is
turned off before you install the US-122
drivers.

ing an Opti-chip controller will work
dependably. These cards (also available
in PCMCIA format for laptops) are
available through a number of manufac-
turers.
PowerBook G3 Series (or later) with
built in USB (or using a 3rd party PCM-
CIA 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. Mac OS versions ear-
lier than 8.6 do not implement full USB
support, and are not recommended.
Again, plenty of RAM and fast drives are
suggested.
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.
Make certain
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-122 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.
