A very thorough, professional explanation of the high speed USB port. I like the fact that the presentation kept on target, no chasing rabbits, just relevant information, presented in a logical format, with great illustrations. For those who dealt with the various data ports that we part of the first PCs, the history of the keyboard, LP1, Serial ports, PCI busses, etc. was very interesting walk through memory lane. Parallel data transfer was once the high speed transfer leader, until technology kept raising the data transfer rate of two-wire serial data transfer. It's too bad that USB connectors took a while to resolve on the popular USB-C format, whose connection is not keyed.
great video, wonderfgreat video, wonderful explanation gained a subscriber, at 32:44 USB-PD will the video still be released? Or is it already posted somewhere? Sorry if the question is stupid, I'm based on the automatic translation of the subtitles made by YT into Portuguese.
WOW is all i can say from the science of the electronic to the actual electrical diagram to the test of the electrical system to the actual practical use and debugging it just WOW 🕶🕶🕶
In addition to the theory of USB designs, manufacturers of cables and accessories to these cables have added features. These features may often be necessary for some users. Earlier products have trouble handling the additional demands now often expected. Especially the increased current flow that the devices at either end of the cables may want to use with the cable. The later standards of USB can theoretically handle these increased power demands (120+ watts) of the earlier designs. These perform differently, depending on the quality and length of the cables. Some cables have magnetic fittings at the device end. These magnetic ends may be removable or changed according to the type of device. Other options include short or longer lengths, adapters, and converters for combinations of plug endings, and coiled cables. Other more common variations exist in the length and physical toughness of the cable & connectors. Additional LED lights may be added to either end or just one end of the cable. Sometimes the whole length of the cable may be lit. It is now possible to buy cables with inbuilt digital current readouts at either end of the cable. The end plugs of the cables may also be in-line, right-angled, or versatile multi-angled, compared to the length of the cable. A rarely mentioned version of the “Micro USB 5 Pin B Male Plug” plug adds the ability to disregard the single “correctness” of the original design. This then allows use similar to the USB-C plug, where the correct connection can be done without 180-degree twisting. My purchases of these rare cables seem not available now.
USB port had more common with PS/2 port instead of serial port... USB port originally only lacked one "used" pin of the PS/2 port, so it was possible to connect same device with passive adapter.
I couldnt find a better video ... my goal was to make my mini FPGA print characters on a LCD using a "USB Keyboard" , so i have to build a logic circuit that simulate USB interface to read the signal of the keyboard .. thanks to you i can probably make it
"Pieces of seven, pieces of seven" - hmm, must be a parroty error... Warning, understanding this joke requires knowledge of classic literature and obsolete serial communication protocols 😄
Nokia was pretty late to join usb game. But they were part of the collection of companies that all agreed to move to use microusb for charging(apple was one of those companies interestingly enough). Most other mid 00's smartphone manufafturers like htc used miniusb for years before.
Basically, yes. Because Windows needs to make sure the write operation is complete. Otherwise you can mess up the filesystem and possibly corrupt data.
Let us be accurate. Sources from internet. Quoted: "USB was invented by Ajay Bhatt 1995, an Intel employee at the time. He led a team from seven companies, Compaq, DEC, IBM, Intel, Nortel, Microsoft, and NEC, to develop the USB standard." "Ajay V. Bhatt[4] is an Indian-American computer architect who produced several widely used technologies, including USB (Universal Serial Bus), Platform Power Management architecture, and various chipset." Yes, I do admit. Little googling has given the fact, that he is actually contributed a lot to the development of USB, both protocol and connector.
oh NO it didn't have any GALVANIC ISOLATION what are we to do? well as for me, I'm going to watch something else because I don't want to waste my time watching shit I don't understand it's that easy
