2.3.4 USB connection
A MSO USB device can be physically connected to other host than Windows™ PC, but the
‘MSO communication protocol over USB’ and a compatible USB driver must be developed
for the host system.
The integrated USB driver of the MSO terminal emulates a RS232 serial port. The MSO
terminal is processed as a Communication Device Class (CDC), in accordance with the "USB
Device Class Specifications, version 2.0" available from the www.usb.org web site, in
"developers, documents" section.
The MSO devices comply with the USB 1.1 standard. They operate in Full Speed mode (@12
Mbit/s) with USB 1.1, USB 2.0, USB 3.0 and USB 3.1 hosts or hubs.
The ‘MSO communication protocol over USB’, is described in the [R2] and [R4] documents.
