USB Device Compatibility

Overview

The Keyspan USB Server hardware (model US-4A) supports USB devices, USB multi-function
printers, scanners, hard drives, HID devices, and other USB devices.
The USB Server supports up to 8 USB devices on one USB Server. While the USB Server only
has 4 USB ports, we support 8 devices due to how Compound USB devices work. Compound
USB devices are devices that have multiple components connected to an embedded USB hub inside
1 USB device. For example, the Lexmark X1150 is a compound device that has 2 components
(one for the scanner, one for the printer). The Canon i475D is also a compound device that has 3
components (the printer, the card reader, and a HID device [for buttons on the printer]).
Tech Note About USB Devices:
Technically speaking, USB devices can either be a single USB device (a USB printer
that contains only one component ie a single button mouse), a composite USB
device (a device that contains multiple components but appears as one device ie a
multifunction printer), or a compound USB device (a device that has multiple
components that are tied together by an embedded USB hub inside the USB device
itself ie a printer with a card reader, a keyboard with a port to connect a mouse, etc.).
Using single and composite USB devices via the USB Server is identical to using them
when connecting to built-in port. By default, compound USB devices also work the
same way as when they are connected to a built-in port however you can OPTIONALLY
configure the USB Server to allow you to connect to certain components of a
compound device instead of connecting every component. This is useful if you just
want to connect the printer component of a multi-function so that you don't get any
message screens regarding the scan component of that device.
The USB Server, part# US-4A, supports ANY USB device provided the USB device:
