Note: The Mbps mentioned in this article is megabits per second, not the megabytes per second we use. One byte is equal to eight bits.
It is necessary to first explain the origin of the USB0 specification. The USB0 specification is jointly developed by Compaq, Hewlett Packard, Intel, Lucent, Microsoft, NEC, and Philips. It increases the peripheral data transmission speed to 480Mbps, which is 40 times that of USB 1 devices! However, according to the original plan, the new USB 0 standard is only intended to set this standard at 240 Mbps, and later, it has been worked hard to increase it to 480 Mbps.
Due to changes in standards developed in 2000, the USB specification produced three speed options: 480 Mbps, 12 Mbps, and 5 Mbps. In June 2003, when the USB0 standard began to gain popularity, the USB Association renamed the USB specifications and standards. Perhaps the USB Association’s move was only to better unify the standards without confusion, but perhaps the USB Association did not expect This standard creates a messy situation for the flash drive and MP3 market.
Renaming the USB standard changed the original USB 1 to USB 0 Full Speed ??full-speed version, and changed the original USB 0 to USB 0 High-Speed ??high-speed version, and announced the new logo at the same time. It goes without saying that the USB 0 speed of the high-speed version certainly exceeds the USB 0 of the full-speed version.
Although the current USB device has been widely used, the USB1 interface is more common, and its transmission speed is only 12Mbps. For example, when you scan a 40M image with a USB1 scanner, it takes half a minute. This speed makes the user feel very inconvenient. If there are several pictures to be scanned, you have to have good patience to wait.
The needs of users are the driving force for the development of science and technology, and manufacturers have also recognized this bottleneck. At this time, COMPAQ, Hewlett Packard, Intel, Lucent, Microsoft, NEC and PHILIPS jointly developed the USB 0 interface standard. USB 0 increases the data transfer speed between devices to 480Mbps, which is about 40 times faster than the USB 1 standard. The biggest benefit for users is that they can use more efficient external devices and have multiple speeds. Peripheral devices can be connected to the USB 0 line without worrying about bottlenecks during data transmission.
So, if you use a USB 0 scanner, it’s completely different. It takes only about half a second to scan a 40M image, and the blink of an eye is over, and the efficiency is greatly improved.
It goes without saying that in the 21st century, many flash drives and MP3s used in MP3s are actually USB1, which was named USB0 by Full Speed ??by the USB Association. The speed is only 12Mbps, which is far from the high-speed version of 480Mbps.
Moreover, USB0 can use the same specifications of the cable in the original USB definition, the specifications of the connector are also the same, maintaining the excellent features of USB 1 under the premise of high speed, and the USB 0 device will not be used together with the USB X device. Any conflicts occur.
