USB features

Universal Serial Bus, or USB, was introduced in 1996. It dramatically simplied the connection between host computers and peripheral

devices like mice, keyboards, external drivers, and printers.

Let's take a quick look on the USB evolution referencing to the table below.

Table 1. USB evolution

Type Data Transfer Rate Category Introduction Year

USB 3.0/USB 3.1 Gen 2 5 Gbps Super Speed 2010

USB 2.0 480 Mbps High Speed 2000

USB 3.0/USB 3.1 Gen 1 (SuperSpeed USB)

For years, the USB 2.0 has been rmly entrenched as the de facto interface standard in the PC world with about 6 billion devices sold, and

yet the need for more speed grows by ever faster computing hardware and ever greater bandwidth demands. The USB 3.0/USB 3.1 Gen 1

nally has the answer to the consumers' demands with a theoretically 10 times faster than its predecessor. In a nutshell, USB 3.1 Gen 1

features are as follows:

• Higher transfer rates (up to 5 Gbps)

• Increased maximum bus power and increased device current draw to better accommodate power-hungry devices

• New power management features

• Full-duplex data transfers and support for new transfer types

• Backward USB 2.0 compatibility

• New connectors and cable

The topics below cover some of the most commonly asked questions regarding USB 3.0/USB 3.1 Gen 1.

Speed

Currently, there are 3 speed modes dened by the latest USB 3.0/USB 3.1 Gen 1 specication. They are Super-Speed, Hi-Speed and Full-

Speed. The new SuperSpeed mode has a transfer rate of 4.8Gbps. While the specication retains Hi-Speed, and Full-Speed USB mode,

54 Technology and components

commonly known as USB 2.0 and 1.1 respectively, the slower modes still operate at 480Mbps and 12Mbps respectively and are kept to

maintain backward compatibility.

USB 3.0/USB 3.1 Gen 1 achieves the much higher performance by the technical changes below:

• An additional physical bus that is added in parallel with the existing USB 2.0 bus (refer to the picture below).

• USB 2.0 previously had four wires (power, ground, and a pair for dierential data); USB 3.0/USB 3.1 Gen 1 adds four more for two pairs

of dierential signals (receive and transmit) for a combined total of eight connections in the connectors and cabling.

• USB 3.0/USB 3.1 Gen 1 utilizes the bidirectional data interface, rather than USB 2.0's half-duplex arrangement. This gives a 10-fold

increase in theoretical bandwidth.

With today's ever increasing demands placed on data transfers with high-denition video content, terabyte storage devices, high megapixel

count digital cameras etc., USB 2.0 may not be fast enough. Furthermore, no USB 2.0 connection could ever come close to the 480Mbps

theoretical maximum throughput, making data transfer at around 320Mbps (40MB/s) — the actual real-world maximum. Similarly, USB

3.0/USB 3.1 Gen 1 connections will never achieve 4.8Gbps. We will likely see a real-world maximum rate of 400MB/s with overheads. At this

speed, USB 3.0/USB 3.1 Gen 1 is a 10x improvement over USB 2.0.

Applications

USB 3.0/USB 3.1 Gen 1 opens up the laneways and provides more headroom for devices to deliver a better overall experience. Where USB

video was barely tolerable previously (both from a maximum resolution, latency, and video compression perspective), it's easy to imagine

that with 5-10 times the bandwidth available, USB video solutions should work that much better. Single-link DVI requires almost 2Gbps

throughput. Where 480Mbps was limiting, 5Gbps is more than promising. With its promised 4.8Gbps speed, the standard will nd its way

into some products that previously weren't USB territory, like external RAID storage systems.

Listed below are some of the available SuperSpeed USB 3.0/USB 3.1 Gen 1 products:

• External Desktop USB 3.0/USB 3.1 Gen 1 Hard Drives

• Portable USB 3.0/USB 3.1 Gen 1 Hard Drives

• USB 3.0/USB 3.1 Gen 1 Drive Docks & Adapters

• USB 3.0/USB 3.1 Gen 1 Flash Drives & Readers

• USB 3.0/USB 3.1 Gen 1 Solid-state Drives

• USB 3.0/USB 3.1 Gen 1 RAIDs

• Optical Media Drives

• Multimedia Devices

• Networking

• USB 3.0/USB 3.1 Gen 1 Adapter Cards & Hubs

Technology and components 55

Compatibility

The good news is that USB 3.0/USB 3.1 Gen 1 has been carefully planned from the start to peacefully co-exist with USB 2.0. First of all,

while USB 3.0/USB 3.1 Gen 1 species new physical connections and thus new cables to take advantage of the higher speed capability of

the new protocol, the connector itself remains the same rectangular shape with the four USB 2.0 contacts in the exact same location as

before. Five new connections to carry receive and transmitted data independently are present on USB 3.0/USB 3.1 Gen 1 cables and only

come into contact when connected to a proper SuperSpeed USB connection.

Windows 8/10 will be bringing native support for USB 3.1 Gen 1 controllers. This is in contrast to previous versions of Windows, which

continue to require separate drivers for USB 3.0/USB 3.1 Gen 1 controllers.

Microsoft announced that Windows 7 would have USB 3.1 Gen 1 support, perhaps not on its immediate release, but in a subsequent Service

Pack or update. It is not out of the question to think that following a successful release of USB 3.0/USB 3.1 Gen 1 support in Windows 7,

SuperSpeed support would trickle down to Vista. Microsoft has conrmed this by stating that most of their partners share the opinion that

Vista should also support USB 3.0/USB 3.1 Gen 1.

Super-Speed support for Windows XP is unknown at this point. Given that XP is a seven-year-old operating system, the likelihood of this

happening is remote.

HDMI 1.4

This topic explains the HDMI 1.4 and its features along with the advantages.

HDMI (High-Denition Multimedia Interface) is an industry-supported, uncompressed, all-digital audio/video interface. HDMI provides an

interface between any compatible digital audio/video source, such as a DVD player, or A/V receiver and a compatible digital audio and/or

video monitor, such as a digital TV (DTV). The intended applications for HDMI TVs, and DVD players. The primary advantage is cable

reduction and content protection provisions. HDMI supports standard, enhanced, or high-denition video, plus multichannel digital audio on

a single cable.

Troubleshooting

Enhanced Pre-Boot System Assessment — ePSA

diagnostics

The ePSA diagnostics (also known as system diagnostics) performs a complete check of your hardware. The ePSA is embedded with the

BIOS and is launched by the BIOS internally. The embedded system diagnostics provides a set of options for particular devices or device

groups allowing you to:

• Run tests automatically or in an interactive mode

• Repeat tests

• Display or save test results

• Run thorough tests to introduce additional test options to provide extra information about the failed device(s)

• View status messages that inform you if tests are completed successfully

• View error messages that inform you of problems encountered during testing

CAUTION: Use the system diagnostics to test only your computer. Using this program with other computers may cause invalid

results or error messages.

NOTE: Some tests for specic devices require user interaction. Always ensure that you are present at the computer terminal

when the diagnostic tests are performed.

Running the ePSA diagnostics

1 Power-on the computer.

2 As the computer boots, press the F12 key as the Dell logo appears.

3 On the boot menu screen, select the Diagnostics option.

4 Click the arrow key at the bottom left corner.

Diagnostics front page is displayed.

5 Press the arrow in the lower-right corner to go to the page listing.

The items detected are listed.

6 To run a diagnostic test on a specic device, press Esc and click Yes to stop the diagnostic test.

7 Select the device from the left pane and click Run Tests.

8 If there are any issues, error codes are displayed.

Note the error code and validation number and contact Dell.

Diagnostic LED

This section details the diagnostic features of the battery LED in a notebook.

Instead of beep codes errors are indicated via the bicolor Battery Charge LED. A specic blink pattern is followed by ashing a pattern of

ashes in amber, followed by white. The pattern then repeats.

NOTE: The diagnostic pattern will consist of a two digit number being represented by a rst group of LED blinks (1 through 9) in

amber, followed by a 1.5 second pause with the LED o, and then a second group of LED blinks (1 through 9) in white. This is

then followed by a three second pause, with the LED o, before repeating over again. Each LED blink takes 0.5 seconds.

Troubleshooting 81

The system will not shutdown when displaying the Diagnostic Error Codes. Diagnostic Error Codes will always supersede any other use of

the LED. For instance, on Notebooks, battery codes for Low Battery or Battery Failure situations will not be displayed when Diagnostic

Error Codes are being displayed:

Real Time Clock reset

The Real Time Clock (RTC) reset function allows you or the service technician to recover the recently launched model Dell Latitude and

Precision systems from select No POST/No Boot/No Power situations. You can initiate the RTC reset on the system from a power o

state only if it is connected to AC power. Press and hold the power button for 25 seconds. The system RTC reset occurs after you release

the power button.

NOTE: If AC power is disconnected from the system during the process or the power button is held longer than 40 seconds, the

RTC reset process is aborted.

82 Troubleshooting

The RTC reset will reset the BIOS to Defaults, un-provision Intel vPro and reset the system date and time. The following items are

unaected by the RTC reset:

• Service Tag

• Asset Tag

• Ownership Tag

• Admin Password

• System Password

• HDD Password

• Key Databases

• System Logs

The following items may or may not reset based on your custom BIOS setting selections:

• The Boot List

• Enable Legacy OROMs

• Secure Boot Enable

• Allow BIOS Downgrade

Testing memory using ePSA

1 Turn on or restart your computer.

2 Press F12 or press Fn+PWR to invoke the ePSA diagnostics.

The PreBoot System Assessment (PSA) starts on your computer.

NOTE: If you wait too long and the operating system logo appears, continue to wait until you see the login screen/

desktop screen. Turn o the computer and try again.

If the memory test results in 25 or less errors, then the RMT basic feature automatically xes the issues. The test will indicate a pass result

since the defect(s) have been removed. If the memory test results in 26 - 50 errors, the RMT basic feature masks the defective memory

blocks and results in pass with no memory replacement requirement. If the memory test results in more than 50 errors, then the test is

stalled and the result indicates that memory module replacement is required.
