| Q1: |
What is a USB hub ? |
| A1: |
USB hub typically consists of a single upstream
port (designed to connect directly to your
computer or to another hub) and multiple downstream
ports. |
| |
|
| Q2: |
How Many USB hubs can I connect together
? |
| A2: |
In total you should only connect 5 tiers
of USB hubs together. A tier is defined by
the number of hubs a device's signal must
pass through before it reaches the host. For
example, using a 4-port USB hub, you could
connect a theoretical maximum of 341 hubs
in five tiers, this would leave you with an
incredible 1024 ports to connect USB devices!
But you should only connect 127 devices together
at any time. |

| Q3: |
What software is needed to get the USB Hub
to work? |
| A3: |
No software is required as long as your
computer can support USB Devices. |
| |
|
| Q4: |
How far can a USB Device be away from the
USB Hub? |
| A4: |
5 meters is the maximum distance between
each connected device and the USB Hub. |
| |
|
| Q5: |
Is a power supply needed for the USB Hub? |
| A5: |
- The power supply is not needed if using
low speed devices (1.5 Mbps) such as joysticks,
mice and keyboards
- For full speed devices (12 Mbps) you
must have the USB Hub in Self-powered
mode. The USB Hub is a full speed device,
so if you are connecting anohter USB Hub,
you must use a power supply with the USB
Hub you are connecting to
- If you are using the 7-Port USB Hub,
you must attach the power supply to access
the 3 side ports
|
| Q6: |
What is the difference between Self-powered
mode and Bus-powered mode? |
| A6: |
- Self-powered mode means the USB Hub
is being powered by an external power
supply. If a device connected to the Hub
needs more power (such as a scanner or
a cascaded USB Hub) you will need to connect
the adapter. The 3 side ports on the 7-Port
USB Hub will only work if in Self-powered
mode
- Bus-powered mode is when there is no
external power supply connected to the
USB Hub. This will allow low speed devices
such as mice, keyboards and joysticks
to work
