2008-08-07 18:54:36	rev. 4	INCORRECT	In the logic of connection of a couple of connectors an elementary rule should be completed and it is that when you put to a cable a plug and a jack these and it introduces the plug in the jack all the threads of the cable they should form a closed loop if this doesn't happen, then there are problems. It is for it that I believe that the pinout of the connector "A" and of the mini-USB they are incorrect. In spanish (por si acaso.) En la logica de conexion de una pareja de conectores debe cumplirse una regla elemental y es que cuando usted pone a un cable un plug y un jack estos e introduce el plug en el jack todos los hilos del cable deben formar un lazo cerrado si esto no ocurre , entonces hay problemas. Es por ello que creo que el pinout del conector "A" y del mini-USB estan incorrectos.	APPROVED

2009-03-12 21:05:32	rev. 6	CORRECT	The information seems correct... "How does USB cable transmit 480MHz data and clock" ?? :: This is achived with an interface such as ULPI, 8 data bits, and 4 control is typically. so theoretically 480/8= 70Mhz (Typical rin speed for a good ARM 7 core 2009) run speed to hit the full Bandwidth. Thats half the story... Peak is 480Mbps, that is typically not sustained for any amount of time, although you can get damn close on fast systems. At any rate it is hardly a: "mistake from marketting - pigheaded marketting bosses"	APPROVED

2012-11-11 23:25:38	rev. 18	ERROR FIXED	First off.. Thank you for doing all this work! Well.. The document is almost completely correct; there are just a few details that could probably be improved. "mouses" IS incorrect. "mice" IS correct. Ask Kensington, a company which makes keyboards, mice and trackballs. Also, it seems to me like the USB A connector is upside down, both the plug and the socket. You can determine what's up and down by looking at most USB sticks; they have a LED on the top-side. On many PCs, USB-accessories (such as keyboards), you'll find that the socket (eg. in a keyboard) has the "thin" side up; this makes the manufacturers of USB-sticks and DVB-T decoders put a LED on the side that is turned upwards when inserted into such keyboards/accessories/PCs. Forgive me if I am misleading anyone; I try my best not to. :)	APPROVED
2012-11-11 23:31:24	rev. 18	ERROR FIXED	I just stumbled over: "USB 1.0 (nowdays obsolete)". nowdays should be nowadays. It is not obsolete. Devices are still being developed, which use USB 1.0. The reason is that there are many microcontrollers, that are quite slow, but just fast enough to support USB 1.0. The Atmel AVR is a good example. Some of them are 'born' without USB, and a USB driver can be made in firmware (see obdev.at). Other examples are cheap ICs, such as the FTDI and PL2303/PL2305 chips. I do not know if FTDI are still making USB 1.0 chips, but I think PL230x is still USB 1.0... No reason to make a full-speed USB chip for a 0.5Mbit RS232-port. ;) The following is not necessary for you to read, I only provide it, in case you're curious. It's an awesome article, which I've learned a lot from: http://www.usbmadesimple.co.uk/	APPROVED

2014-10-21 21:15:19	rev. 29	ERROR FIXED	Just a comment on the shield. Apple Lightning cables do not have a ground wire, they use the shield for return. So far every Phone I have checked ties the shield to their power ground. If the host also ties to power ground, and my PC does, then the shield becomes the main return. This surprised and confused me at 1st. Also the USB specification does not clearly state what to do with the shield, it states something along the lines of terminate in the customary way. Just thought this was interesting and passed it along. I think the phones take advantage of this when charging because it helps keep the voltage level up. I don't like the idea that the EMI shield is now carrying current but that is what happens.	APPROVED
