About USB 2.0 Performance
For your XHub2 and USB 2.0 devices to operate at USB 2.0
speeds, the XHub2 must be connected to a USB 2.0 port,
and USB 2.0 drivers with hub support must be installed on
your computer.
If your computer does not have a built-in USB 2.0 port,
Adaptec recommends connecting your XHub2 to an
Adaptec USB 2.0 adapter for the highest-quality USB 2.0
connection.
Note: USB 1.1 devices won’t operate at USB 2.0 speeds,
even if they’re connected to a USB 2.0 hub or adapter.

Plugging in Your XHub2
Follow the picture to connect your XHub2. You don’t have
to power off your computer before connecting the hub.
You do not need to install any device drivers. When your
XHub2 is connected and your computer is powered on,
your hub is ready for use.
Unplugging Your XHub2
Your XHub2 is hot-pluggable, which means it can be
connected
and disconnected while your computer is on.

may not be hot-pluggable, however; see
Unplugging Your Devices on page 3 for more information.)
