USB 1.1 & 2.0 SimilaritiesUSB 1.1 & 2.0 Similarities

Connectors and cables are the same 2.0 is backwards compatible with 1.1 No difference in use model to end user Market is currently PC centric

USB 2.0 ChangesUSB 2.0 Changes

Max data rate is 480 Mb/s (40X increase) Windows 2000 or XP only Stringent current tests Critical signal integrity measurements Auto speed sensing 1.5/12/480 Mb/s

What Are The Challenges?What Are The Challenges?

480 Mb/s is a 40X increase USB 2.0 devices must be compatible with USB 1.1 A hub must communicate with up to 7 peripheral

devices and 5 hubs. Data transfer rates of 1.5Mb/s, 12Mb/s, 420Mb/s,

isochronous, and bulk Current and signal integrity requirements are

stringent

Typical ProblemsTypical Problems

Enumeration Failure Bad End of Packet Inrush current exceeds specification Data valid window on D+ and D- outside of

limits Device fails to go into suspend mode
