•
“Plug and Play” capability: this incredibly convenient function eliminates
any need to turn off or restart the computer when connecting a new
peripheral. Just plug it in and off you go.

What is the difference between USB 1.1 and USB 2.0?
The main difference is speed. USB 1.1, the original version of the interface, is
capable of throughput up to 12Mb/s. USB 2.0 supports data speeds up to 480
Mb/s, making it 40 times faster than its predecessor. This increased bandwidth
translates into higher performance in demanding applications requiring high
transfer rates.

What are the ideal uses for USB 1.1?
USB 1.1 is ideal for more traditional connections such as keyboards, mice,
joysticks and scanners. With its 12Mb/s speed, it can also be used for more
advanced applications such as games and audio software, as well as storage
on hard disks, CD-RW, and other drives. USB 2.0 devices will have far superior
performance in these more demanding applications, however.

What are the ideal applications of USB 2.0?
Except low-end devices, such as mice and keyboards, virtually any hardware
will benefit from the extra bandwidth provided by USB 2.0. PC video
conferencing applications will be further enhanced by the usability of USB 2.0
digital video cameras. The new breed of USB 2.0 video capture adapters will
enable professionals and consumers alike to record the highest video quality
possible. USB 2.0 scanners will raise the performance bar by offering speeds
that match SCSI and FireWire scanners, at a more affordable price. And USB
2.0 storage devices, such as CD-RW, DVD-RAM and DVD-R/RW, and
removable cartridge drives, will also benefit from the new I/O performance.
