Understanding Usb Connections - Epson EXPRESSION 1640XL User Manual

Understanding USB connections

USB Cables
USB cables enable you to connect or remove peripherals to and
from your computer easily, without having to shut down and
restart the system each time a peripheral is plugged in or
unplugged. You do not have to set an ID number or a terminator.
Note:
Do not connect or disconnect USB cables when the scanner is in use.
USB cables have 2 different connectors at each end.
Type A connects to your computer.
Type B connects to your scanner.
USB hub
You can also use a USB hub, allowing you to increase the number
of USB ports and therefore connect several peripherals.
Note:
If you connect your scanner through more than one hub, your system
may not work properly. In this case, try connecting the scanner directly
to the computer's USB port. Also, your system may not work properly
if you use a USB cable other than that supplied by EPSON.
