"IMPORTANT: Do not connect or disconnect bus-powered M-Audio, or 3rd party FireWire devices
while your computer is running (i.e. no “hot-plugging”). Make all FireWire cable connections while the
computer is powered off.
Reports have come to our attention of isolated problems when hot-plugging IEEE 1394
(aka “FireWire”) devices, including, but not limited to devices of the M-Audio FireWire family.
Hot-plugging refers to making connections to1394/FireWire ports while one or more of the
devices (including the computer) are still powered on. There have been rare occurrences when,
after hot-plugging, either the FireWire peripheral or the host computer’s FireWire port are rendered
permanently inoperable.
Please consult the Knowledge Base in the Support section at www.m-audio.com for updates on this
important issue."
