Thank you for purchasing the RadioShack
USB 2.0 4-PortUSB Hub. This hub supports
a transmission rate of up to 480 Mbps
(megabits per second) which is 40 times
faster than the USB 1.1’s 12 Mbps and the
IEEE 1394 firewires’ 400 Mbps transmission
rate. It is fully compatible backward with
USB Revision 1.1 devices and allows your
existing USB devices to function as usual.
The hub’s four external downstream type-A
USB ports allow you to connect four USB
devices such asa keyboard, mouse, printer,
scanner, or camera that can all function
simultaneously.
By sharing its increased bandwidth, the
4-port USB 2.0 huboffers highperformance
through multiple peripheral device
connections. Peripheral devices requiring
high speed transmission rates, such as
external storage devices, scanners, DVD
drives, CD-RW drives, MO (Magneto-
Optical) drives, digital cameras, and
camcorders, normally require the use of the
more expensive firewires (IEEE 1394). The
USB 2.0 hub can satisfactorily support these
peripherals at a huge cost savings.

• You must use a Class 2 power
source that supplies 5 volts DC
and delivers at least 2.5 Amps. Its
center tip must be set to positive
and its plug must fit the USB hub's 5VDC
2.5A jack. The supplied adapter meets these
specifications. Using an adapter that does
not meet these specifications could damage
the USB hub or the adapter.
• Always connect the AC adapter to the USB
hub before you connect it to AC power.
When you finish, disconnect the adapter
from AC power before you disconnect it from
the USB hub.

Q: Why won’t my USB camera (or other
USB device) work through the USB hub?
A: Make sure the driver for the device is
installed on your PC, the device’s power
is connected, and the USB hub’s AC
power adapter is properly connected. If
all three conditions are met and the USB
hub still does not detect the device,
disconnect and reconnect the device to
the USB hub.
Q: Why won’t the POWER LED on the top
