Understanding E5813A and USB Hubs

E5813A Networked 5-Port USB Hub
Hubs, critical components in the plug- and- play architecture,
are wiring concentrators that enable the attachment of multiple
devices, thus converting a single attachment point into multiple
attachment points.
The E5813A is a LAN to USB converter. As such, LAN traffic
can and will introduce some level of non- deterministic delays.
For example, if you are using USB to RS- 232 devices connected
to the E5813A, you should turn on hardware flow control
(RTS/CTS or DTR/DSR) for data transfers.
Also, the USB architecture allows a cascaded multiple hub
configuration with certain power limitations (explained later in
this section). See figure 1.
Figure 1
Each hub has an upstream port, connecting to the host, and
multiple downstream ports, connecting to downstream devices,
including other hubs. A hub can detect attachment and
detachment of downstream devices and enable and monitor the
distribution of the power to downstream devices via their
integral hardware and the operating system.
