Demo3 – USB 3.0 Host System Selection

...

Introduction

Image Removed
ON Semiconductor's Demo3 interface board uses USB 3.0 ("Super Speed" USB) to provide improved performance over its predecessor. Since this technology is roughly 10 times faster than previously used on the Demo2/2X, the host system requirements have changed. This presents Demo3 users with new considerations when selecting a desktop or laptop system. This document will discuss options for new equipment purchasers or those attempting to upgrade their existing systems.

Update - Read this First!

November, 2018; there have been many USB 3.0 Controller (aka "chip-set") improvements since this document was first created.  The most significant has been the fairly universal acceptance of the Intel-USB-eXtensible-Host-Controller in all new Desktop and Laptops. This chip-set has proven to work well with the Demo3.

The easiest method of determining Compatibility is to do a Web search for the USB Chip-set driver for the given make / model. For example, for a Dell 7480 USB Chipset driver, one of the links the search results in is for the Intel-USB-eXtensible-Host-Controller.

For all new Desktops and Laptops, it has been found that the USB chip-set driver is out of date, and may likely not recognize the Demo3 and will need to be updated.

New - Trouble-Shooting Guide

The following are the most common issues with the Demo3, and their solution.  Please refer to the Quick Start Guide for other critical information about the DevSuite HW and SW.

• "Camera not found" Warning
  • Check the compatibility list below, and if not found, do a Web search for your make / model of Desktop / Laptop for "USB Chipset driver" - if it is not "Intel-USB-eXtensible-Host-Controller" get another Desktop / Laptop.
  • Disconnect and re-connecting the USB cable, waiting 5 seconds, and then try the DevWareX Probe again. 
  • If that doesn't work, then check for a newer USB chip-set driver by doing a Web search for your make / model of Desktop / Laptop for "USB Chipset driver".
• "DEMO3 does not run reliably on USB 2.x port" Warning
  • First, determine if you are connected to a USB 3.0 port.  Most new Desktops / Laptops do not have USB 2.x ports.
  • Check for a newer USB chip-set driver by doing a Web search for your make / model of Desktop / Laptop for "USB Chipset driver".
  • Newer Desktops / Laptops now have USB 3.1 ports.  If that is the case, ensure that your Demo3 HW revision is 7 or higher - the revision is printed on the back of the board. If less than 7, contact ON Semiconductor Sales.

Background

To fully realize the performance of the Demo3, it must be attached to a computer that contains a USB 3.0 host controller. USB 3.0 was a relatively young technology at the launch of Demo3 (mid-2012). The availability of integrated USB 3.0 hosts was sparse, but has increased steadily. For now, it is necessary to characterize system support of USB 3.0 (and subsequently Demo3) into the following categories:

• Integrated – A USB 3.0 host controller is provided by the system motherboard, either incorporated into the chipset or via a dedicated part. Users in need of new systems should consider this route.

• Add-in (compatible) – The system will accept an add-in card that provides the USB 3.0 host. Users wishing to upgrade their existing machines should consider this option.
  • Desktops – Typically, a free PCI Express (PCIe) x1 slot is required. The slot must be complaint with the PCIe 2.0 specification (sometimes referred to as Generation 2 or Gen2).
  • Laptops – An ExpressCard slot is required. The slot must be compliant with the ExpressCard 2.0 specification.

• Add-in (limited functionality) – Some machines may physically accept the add-in solutions, but do not meet the specification requirements. So for example, an older desktop with PCIe 1.0 compliant slots will only operate the USB 3.0 adapter card at half-speed. This is not a recommend option and should only be considered as a temporary solution. Users should be aware of the following points and decide accordingly:
  • Pros – Faster than USB 2.0 speed. More available bus power to the device, 900mA vs. 500mA.
  • Cons – Half of USB 3.0 speed. Timing critical issues may be hidden. Not supported, the Demo3 Team will not be able to fix any problems specifically arising from this usage.

• Incompatible - Legacy systems incapable of accepting adapter cards or systems that have compatibility issues with the Demo3.

As this technology matures and is widely adopted, we expect this to be less critical to track.

Working with Renesas, AMD added USB 3.0 support to their chipsets in 2011. This began with the A70M and A75 Fusion controller hubs (FCH). Cypress Semiconductor has confirmed Demo3 functionality (exact model TBD).

ASMediaTechnology Inc.

(http://www.cypress.com/?id=4&rID=58617)
Cypress Semiconductor has documented issues with the ASM104x using driver version 1.14.1.0. They recommend downgrading to the driver version 1.10.1.0 when using FX3 based devices. From the Demo3 Team's testing with HighPoint Technology's RocketU 1144A card, we have not seen this solution to work for the Demo3. At this time (5/22/2013) we do not recommend solutions based off the ASMedia part.

The 7 Series Chipset family is the first Intel chipset to integrate a USB 3.0 host controller. This is also the chipset that supports the Ivy Bridge family of CPUs (3^rd generation Core Family) and was released in mid-2012.
Intel 7 Series Chipsets are recommended for use with the Demo3.
Tip: if a system contains a Core i7/i5/i3 3xxx series processor, then it uses a 7 Series Chipset.
Required: For proper operation with Intel 7 Series chipsets, the Demo3 needs to be running E.106 (boot firmware), E.20B (firmware), 26 (FPGA), or later. Use the HardwareUpdate Tool to check the current firmware loaded on the Demo3 and update the Demo3 if necessary. Note that newest available version will be displayed on the next dialog as each item is selected, and it may not match the versions listed here.

1. μPD720200
2. μPD720200A
3. μPD720201 & μPD720202

These are recommended for use with the Demo3.
NEC/Renesas does not produce their own solution; they supply their USB 3.0 part to 3^rd party motherboard and add-in adapter vendors. Most vendors just copy the reference design, so all the add-in adapters will appear approximately the same and are able to use a common driver. There is no one solution better than another and this allows flexibility in purchasing. Some known NEC/Renesas based add-in adapter models for reference (in no way comprehensive):

...

External hub and PCIe adapter card solutions using the VIA VL800 part have been tested in-house with the Demo3.
The VL800 is recommended for use with the Demo3.

Others

Nvidia, Texas Instruments, etc. are also known to be working on or have released USB 3.0 host controller solutions. Demo3 has not yet been tested with any of these.
