However, USB 3.0 ports include an additional row of five pins therefore, USB 3.0 compatible cables will have nine wires. The inner pins carry data (D+ and D-), and the outer pins provide a 5-volt power supply. In terms of USB power specifications, a standard USB 1.0 or 2.0 port contains four pins, and the applicable USB cable has four wires. Take, for example, connecting your smartphone to your laptop to transfer music files or photos. Moreover, the flow of power is always from host to device, but data can flow in either direction. In nearly every instance, a computer is the host, whereas a tablet, camera, or smartphone is the device. In any USB network, there is one host and at least one device. This, of course, affords USB a myriad of new uses, including system backups, increased gigabit Ethernet adapter performance, and the ability to handle large video files.

Now, with the USB 3.0 series standard, power output nearly doubled, and the data rate increased by a multiple of 10. These increases in functionality correlate with the increase in data rates and the improvements in output power. However, with USB 2.0, it afforded the use of flash drives and other external hard drives. For example, with USB 1.1, it was functionally compatible with keyboards, mice, and printers as a connection option. This includes USB standards, and it is evident by the increase in functionality as the standards evolved. In every instance, when dealing with power and electronic devices, power matters. The Effects of USB Power Output and Data Rates The five overall main speeds of the USB standards are as follows: However, like its predecessor, USB 3.0 is backward compatible with USB 2.0, albeit the USB 2.0-speed limitations still govern you. The USB 3.0 series standard, which includes USB 3.1 and USB 3.2, is the current de facto standard in USB. Also, with the increase in data rate comes an increase in bus power, i.e., from 500 mA (USB 1.1 and USB 2.0.) to 900 mA (USB 3.0). USB 3.1 (10 Gps) has an increase in data rate speed compared to USB 3.0 (5 Gbps). Moreover, it is being called the one-port revolution since USB 3.0, and USB 3.1 are physically identical.

The USB 3.0 standard is, of course, the next iteration in the universal serial bus standard. USB has come a long way since its inception however, remains a standard. The specifications for USB 2.0 include a data rate of 480 Mbps, and this increase afforded the use of external hard drives. Also, with the newer standard came increased data rates. In the spring of 2000, the USB 2.0 standard supplants USB 1.1 as the defacto USB standard. Like all things in the field of electronics, the USB standard progressed and evolved, thus ushering in the standard USB 2.0. However, with USB 1.1, this all changed, and even the peripheral manufacturers added USB connections to their devices. During this time, the number of different types of ports on a PC’s motherboard was staggering. To put it mildly, USB 1.1 was a game-changer in the field of computers and peripherals alike.

So much so that it persuaded PC manufacturers to implement them into their board designs. Although by today’s standards, a maximum transfer rate of 1.5 Mbps (USB 1.0) and 12 Mbps (USB 1.1) is nearly unfathomable, back then, these standards set the bar.

The first standard for USB, called USB 1.0, dates back to the 1990s. This becomes especially important when the device you wish to charge or use requires a USB 3.0 port, and the device you want to use only has a USB 2.0 port.īrief History of the Universal Serial Bus The USB port is an indispensable component and thus requires the understanding that not all USB ports are the same. The fact that we are in our third series generation for the component speaks volumes to its popularity and widespread use. The USB port has bridged the gap of communication between a myriad of devices that are otherwise physically incompatible. Some end-users even base their desktop and laptop purchases on whether there are enough USB ports. Over the last decade, the USB port has been the most recognized component in electronics, aside, of course, from the smartphone.
