USB 2.0 FAQ
How fast is USB 2.0?
USB 2.0 will be 480 Mb/sec, 40 times faster than USB 1.1. With protocol
and packet overhead, the maximum data throughput is approximately
How far away from a host can
a peripheral be located?
The maximum cable length is 5 meters for a single cable and extending up to 30
meters, using 5 hubs.
How many devices can be
connected to one host?
You may connect up to 127 devices to a single host.
What's the status of Hi-Speed USB
2.0 in the marketplace?
Hi-Speed USB 2.0, the technology that extends the speed of the peripheral-to-PC
connection up to 40 times over existing capabilities, is now market ready. In
fact, dozens of Hi-Speed USB 2.0 products are now in the market in the U.S.,
Japan, and elsewhere. XP drivers are currently available from Microsoft. 98Se,
ME, 2000 drivers are available from 3rd party vendors (Orange Micro and
Adaptec). Expect to see USB 2.0 PCs shipping in Q3 2002 as Intel's 845 chipset
hit the mass market with integrated USB 2.0 controllers.
What are the benefits of Hi-Speed
USB 2.0?
The higher bandwidth of Hi-Speed USB 2.0 will support the most demanding PC user
applications, such as digital image creation and web publishing, where multiple
high-speed peripherals will be running simultaneously. Hi-Speed USB 2.0 is
expected to replace USB 1.1, which is already a ubiquitous connector on PC
systems today for such peripherals as keyboards, mice, joysticks, removable
storage, printers and scanners.
When was the final USB 2.0
specification released?
The spec was released at WinHEC in April 2000.
Who developed the USB 2.0 spec?
The USB 2.0 spec was developed by a team of seven industry-leading companies,
collectively named the USB 2.0 Promoter Group. The group consists of Compaq,
Hewlett Packard, Intel, Lucent, Microsoft, NEC, and Philips.
Since Hi-Speed USB 2.0 is now
about the same speed as IEEE 1394a, don't they compete?
No. Hi-Speed USB 2.0 is expected to become ubiquitous on all PC platforms
because it is more easily integrated into the core chipsets, at which time it
will become the preferred connection for PC peripherals. IEEE 1394's primary
target is audio/visual consumer electronic devices such as digital camcorders,
digital VCRs, DVDs, and digital televisions. Therefore, the two connections will
differ primarily in application focus.
What is USB On-the-Go?
The supplement to the USB 2.0 specification is expected to be available in early
2002. It is currently under development by a subcommittee authorized by the USB
2.0 Promoter Group, the original developers of the USB 2.0 specification.
Is Microsoft supporting Hi-Speed
USB 2.0 in Windows XP?
Microsoft fully supports Hi-Speed USB 2.0, and has been working to develop
driver support since its inception. Microsoft currently has production Windows
XP drivers available and is expected to have Windows 2000 drivers available by
the end of the year."
Which Intel P4 Motherboards
support USB2.0?
Intel ICH4 Southbridge chipsets support built-in USB2.0 EHCI. These are
included on the 845G, 845GL and 845E chipset family. A list of current Intel
motherboards can be found at: http://developer.intel.com/design/motherbd/flex.htm
