Using FireWire and USB Devices With The Tango 2.0
Known Issues and Advice
FireWire and USB interfaces have many technological advantages over older
interfaces such as ADB, Serial, and SCSI, not the least of which is hot-plugging
capability. However, there are some limitations you should be aware of, and we
have listed some additional advice here. Refer to the peripheral manufacturers’
web sites and user’s guides for more specifi c information.
• Many peripherals require additional drivers and application software to
operate or have full functionality. Software should be included with the
device, or available to download from the manufacturer’s web site. Check the
peripheral’s user’s manual for information about necessary software.
• Mac Users: While USB keyboards and mice are compatible with Tango 2.0,
certain functions cannot be supported on pre-G3 machines; this is an Apple
ROM issue and not a problem with the Sonnet Tango 2.0. Because pre-G3
Macintosh computers were built before Apple added onboard USB support,
certain features, including keyboard startup, wake from sleep (by pressing a
key or moving the mouse), and others, will not work. We recommend that
you keep an ADB keyboard and mouse connected to your system to support
such functionality.
• Mac Users: When the Tango 2.0 is installed in a pre-G3 Macintosh computer,
connected FireWire drives cannot be used as the system startup (boot) drive.
• Mac Users: Always unmount a drive from the desktop (“eject” it or drag it to
the trash) before disconnecting it from its cable or the Tango 2.0 card.
• Windows Users: Always “stop”, “unplug”, or “eject” any drive connected to the
USB or FireWire ports before disconnecting it from its cable or the Tango 2.0
card.
• Disconnecting USB or FireWire peripherals (including external storage devic-
es, cameras, memory card readers, printers, etc.) while they are transferring or
receiving data, may result in damage to the fi le(s) being transferred or cause
your system to hang.
• Remember to connect external power supplies to the peripherals that require
them. Although many peripherals may draw power directly from the Tango
2.0 card, other devices require an external power source.
• When a high-speed USB 2.0 peripheral is connected to a USB 1.1 peripheral,
which is in turn connected directly to the Tango 2.0, the high-speed USB 2.0
peripheral will operate at USB 1.1 speeds. Keep USB 2.0 and USB 1.1 devices
connected separately.
• Should you need to connect high-speed USB 2.0 peripherals to a hub, be sure
to use a USB 2.0 hub; high-speed USB 2.0 peripherals connected to a standard
USB hub will operate at USB 1.1 speed.
• When transferring data from a digital video camera using a FireWire port on
the Tango 2.0, we do not recommend using another FireWire device at the
same time.
• Do not connect FireWire devices in a loop, nor terminate a FireWire chain;
there are no terminators or ID settings required for any FireWire device.
