Connection options
The U170 may be attached to a PC through any USB 2.0 compliant connection method. This
includes the use of USB 2.0 hubs, USB 2.0 extension cables, and USB 2.0 active extenders.
Each segment of a USB connection from device to host, device to hub, or hub to hub, must be
no longer than 5 meters. The USB 2.0 specification states that a total of 4 hubs may be used
downstream of a PC before the U170 device itself. Because the U170 is dependent on USB bus
power, a powered hub should always be used directly upstream of a U170 when not directly
attached to a PC.
Note: USB devices (ex. Flash memory stick) connected downstream of a U170
will be assigned to the session logged in to that U170 device.
Note:
T
he U170 device is powered
by the USB bus and a single USB port can
provide power for only one U170 device with a mouse and keyboard. Adding
additional USB devices immediately downstream of the U170 that draw too
much power is likely to cause errors. Using a powered USB hub downstream
from a U170 for high power peripherals is recommended.
