Use in article (WP:NFCC#7) | USB hardware |
Purpose of use in article (WP:NFCC#8) | Minimum allowable voltages allowed throughout a typical USB network topology. |
Not replaceable with free media because (WP:NFCC#1) |
The software or website from which the screenshot is taken is copyrighted and not released under a free license, so creation of a free image is not possible. |
Not replaceable with textual coverage because (WP:NFCC#1) |
The volume of information (number of different values and location of each value) makes it impractical to implement in text or a table. |
Minimal use (WP:NFCC#3) | This is a single image from a 650 page technical specification, and the section this image is from alone is nearly 100 pages. It's use is as minimal as possible.
It is to be used in an article about this (and other) USB specifications. |
Respect for commercial opportunities (WP:NFCC#2) |
The use of a low resolution screenshot from software or a website will not impact the commercial viability of the software or site. |
Other information | This is from the freely and publicly available technical specification for USB 2.0. It is published by the USB Implementers Forum (USB IF), but is copyrighted to the individual corporations which make up the USB IF. |
