WebSites USB 2.0 Full speed vs. High speed Although USB 2.0 devices are capable of higher speeds than the USB 1.1, not all devices take advantage of this ability. USB 1.1 devices transfer data at either 1.5Mbps (low speed) or 12 Mbps (full speed). USB 2.0 devices operate at both of these speeds, (for backwards compatibility) and if designated as "high speed" device, can transfer data at 480 Mbps if used with a USB 2.0 port. However. simply because a device is designated as USB 2.0, it does NOT mean it is capable of operating at High Speed (480 Mbps). It simply means that it is compliant with Revision 2.0 of the USB specification. USB 2.0 devices rated at "full speed" operate at 12 Mbps and are not any faster than a similar USB 1.1 device. If you need the fast data transfer speeds USB 2.0 can offer, look for devices that are specifically designate "High Speed", and for the special logo displayed below..

USB ports began to appear on PCs in 1997, and Windows 98 was the first Windows to support it natively. Within a few years, USB became popular for connecting nearly every external peripheral device. Replacing the serial and parallel ports on a PC, at least four USB ports are standard on every computer. Hot Swappable USB devices can be connected to without turning the computer off, enabling removable devices to be plugged and unplugged as needed. This feature, combined with easy-reach ports on the front of the computer case, gave rise to the ubiquitous USB drive (see USB drive USB 1.0 and USB 2.0 USB has a maximum bandwidth of 12 Mbps for USB 1.0 and 1.1 and 480 Mbps for Hi-Speed USB 2.0. Up to 127 peripheral devices can be attached to the bus, and USB 1.1 devices can plug into USB 2.0 ports. Fast devices can use the full bandwidth, while low-speed ones can use a 1.5 Mbps subchannel. USB Hubs A USB hub provides additional ports for the user. Like any other USB device, the hub plugs into a USB port on the computer and provides four or more USB ports for peripherals. The peripherals themselves may also contain hubs. For example, a monitor may have a built-in USB hub in order to provide a convenient desktop location for plugging in other devices.

It is widely used for downloading video from digital camcorders to the computer. Also known as the IEEE 1394 standard, the i.Link connector and the High Performance Serial Bus (HPSB), the first version of FireWire supported 100, 200 and 400 Mbits/sec transfer rates and a distance of 4.5 meters between devices. IEEE 1394b provides 800, 1,600 and 3,200 Mbps speeds, increases cable distance to 100 meters and can use glass or plastic fiber and Cat 5 Ethernet cable. FireWire 800 was the first implementation of 1394b and became available in 2003. Backward compatible with FireWire 400, earlier devices run at the lower speed. FireWire supports hot swapping, multiple speeds on the same bus and isochronous data transfer, which guarantees bandwidth for multimedia operations. FireWire Connectors The 6-pin socket is commonly found on desktop computers. A 4-pin version is used on laptops. The faster FireWire 800 requires a 9-pin connector.

There is a limit of 5 levels of branching hubs per controller. Up to 127 devices may be connected to a single host controller, but the count must include the hub devices as well. A modern computer likely has several host controllers so the total useful number of connected devices is beyond what could reasonably be connected to a single controller. There is no need for a terminator on any USB bus, as there is for SPI SCSI and some others.

Interfacing techniques and questions on them General information This page concentrates on links to inter-IC serial buses. When this page talks about 2-wire or 3-wire interfaces, this wire number is the number of control lines. In addition to this those interfaces generally need a common ground, which is the ground plane in circuit board applications and a seprate wire in inter-circuit-board connections. The serial bus interfaces are widely used for interfacing EEPROMs, data converters and many peripheral chips to microcontrollers. They are also often used for inter-microcontroller communication. Serial bus system are also used to build control buses inside equipments like TV receivers, AV amplifiers and cellular phones. The major advantage of usign s serial bus is the small number of wires needed. A major disadvantage of serial interfacing is the tradeoff of speed for space. The processor’s I/O port spends a relatively large amount of time communicating with a serial device. Consequently, serial converters with throughput rates above 500 ksps are uncommon.

(9 printed pages) Contents Introduction USB System Architecture USB Support in Windows CE 2.1 For More Information Introduction As its name suggests, Universal Serial Bus (USB) is an external bus architecture for connecting USB-capable peripheral devices to a host computer. USB was not designed to be used as the internal bus for connecting CPUs to main memory and other motherboard-resident devices. Instead, USB is a communication protocol that supports serial data transfers between a host system and USB-capable peripherals. USB technology was developed as a solution to the increasing end-user demands on computers and the need for flexible and easy-to-use peripherals. A number of standard PC peripherals such as keyboards, mice, joysticks, digital cameras, CTI (computer telephone integration) and Video conferencing products benefit directly from USB. USB offers a number of benefits to system designers: USB provides a single, well-defined, standard connector type for all USB devices. This simplifies the design of USB devices as well as simplifying the end-user's task at figuring out which plugs go into which sockets.

The USB Seal Introduction In Part I, we reviewed the history of USB, going over some of the communication advantages of USB over RS-232, and then touching on the various USB data transfer protocols. USB is a somewhat complex communications protocol but like many things, if you take it one step at a time, it can be digested. In this issue, we will recap some of the basics as well as get into more of the details involving the Windows drivers and their requirements. Also, we will go over some of the capabilities, shortcomings, and limitations of USB. Again, we are covering here the USB 1.x spec dealing with the low speed 1.5Mbps and high speed 12Mbps transfer rates. USB 2.0 devices (480Mbps rates) are not expected to have support from Windows until late 2001.
