MOTU UltraLite- mk3 Hybrid User Manual page 19

If you are connecting via USB2
Some USB ports on computers are USB Version 1.1
ports, which support low-power, low-bandwidth
peripherals such as your computer's mouse and
keyboard. USB 1 ports do not support the high-
speed operation necessary for the UltraLite-mk3. If
you are not sure if the USB ports on your computer
are Hi-speed USB2 or not, check your computer's
documentation. Or check your computer as
follows:
On the Mac, you can run System Profiler (Apple
■
menu> About This Mac> More Info...) to view the
specifications for each USB port on your Mac.
Look in the hardware list for USB and click it. If the
USB bus description on the right-hand side says
USB High Speed Bus, then your Mac has USB2.
On Windows, open Device Manager and expand
■
the Universal Serial Bus section. There should be
an "Enhanced" USB host controller present.
☛
Due to the way all USB 1.1 and USB 2.0
devices share bandwidth, you will achieve better
overall performance by placing 1.1 and 2.0 devices
on separate busses, if possible. For details, refer to
the tech support database at www.motu.com.
1 Before you begin, make sure your computer and
the UltraLite-mk3 are switched off.
2 Plug the flat "type A" plug of the UltraLite-mk3
USB cable (included) into a USB2-equipped socket
on the computer as shown below in Figure 4-1.
3 Plug the squared "type B" plug of the USB cable
into the UltraLite-mk3 I/O as shown below in
Figure 4-1.
