What you need to know...
• If you plug mini Pal into a USB 2.0 port on your computer, individual USB
devices attached to mini Pal will operate at either USB 2.0 or USB 1.1 speeds,
according to the type of USB interface each device has. If your mini Pal is
plugged into a USB 1.1 port on your computer, all connected devices will
operate at USB 1.1 speeds (up to 12 Mbps).
• A USB port can support only one USB device (you cannot daisy-chain USB
devices). If you want to connect more than four USB devices to your mini
Pal, you can plug a USB hub into one of the USB type A ports on your mini
Pal, and then plug additional devices into the hub.
• mini Pal's USB ports can be used in any order.
• Some USB devices, such as some scanners and Flash card readers, can
be bus-powered. This means they do not need to be plugged into an AC
outlet; they can get their power via a USB connection. mini Pal's USB 2.0
hub can supply up to 2.5 Watts of power from each USB type A port, with
a maximum of 5 Watts for all four ports. The combined peak power of all
attached, bus-powered USB devices cannot exceed 5 Watts. For example,
you can connect two 2.5-Watt devices, or four 1-Watt devices...etc. AC-pow-
ered devices will not draw power from the USB connection.
• Even if you turn off your mini Pal, connected USB devices will still be opera-
tional as long as the mini Pal is plugged into an AC outlet.
