System Requirements
The USB204B requires the following basic host PC features to
operate:
•
A host PC that supports the Universal Serial Bus (USB)
•
A PC operating system with a generic USB hub driver,
including Microsoft Windows 95 (OSR2.1 or later), 98, 2000
Hub Operation
The USB204B is a device used to extend the host PC USB
interface. The hub supplies 4 additional USB ports to attach to
devices or other hubs.
Accton’s USB204B can be bus-powered, conveniently
drawing power from the Universal Serial Bus. Therefore, the
host PC has the ability turn on or off any hub, individual port,
or a device attached to a port. The USB204B also supports the
energy-saving suspend, resume and remote wake-on-ring
functions. What’s more, the hub and each downstream port
are overcurrent and short-circuit protected.
Please note the following general points about USB hub
operation:
•
Hubs and devices are hot pluggable and can be connected/
disconnected at any time, even while the host PC is
powered on.
•
Hubs can be daisy-chained up to 5 deep in series, or in any
combination that does not exceed 127 devices.
•
Hubs are dual-powered devices. They can be powered via
the upstream connection (bus powered), or by an optional
power supply (self powered).
•
When bus-powered, downstream ports support only “low-
power” devices, such as a mouse, keyboard or a self-
powered hub.
•
When self-powered, downstream ports can support “high-
power” devices, such as a printer or a bus-powered hub.
Note:
A USB204B must be self-powered by an optional power adapter
to daisy-chain to another hub that is only bus-powered.
