Why is the USB-C market turmoil still in 2022?

BingMag.com Why is the <b>USB-C</b> <b>market</b> <b>turmoil</b> <b>still</b> in 2022?

The USB-C standard offers many benefits such as data transfer, video, audio and charging, but widespread turmoil in the USB-C market has resulted in exactly the same cables. In appearance, they have very different capabilities.

This confusion is the result of the lack of mandatory rules for cable companies and gadgets equipped with a USB-C port, and has forced us to use phones, laptops, tablets. , PCs, cameras and other gadgets Let's make different USB-C cables that are not different in appearance but their function is very different. Sometimes we even see that two USB-C charging cables are different in terms of charging power and it is not possible to use the same cable for two phones.

The complexity of the USB-C device market

is one of The reason for the complexity of USB-C is that for every feature such as power transmission, data and video, there are different and sometimes contradictory specifications and features that few people understand. So you can not unplug every cable and expect it to do all this.

But how do you properly identify the USB capabilities of a cable or device? There are two ways to do this, which include checking the information on the cable package or itself. To do this, you need to look for logos related to the USB standard organization called USB-IF. However, not all manufacturers follow this convention and specify different specifications for data transfer or power on the packaging or product.

Before we talk about the controversy between manufacturers and USB-IF, I have to talk about the status of data transfer and charging standards in the USB-C standard itself to see how chaotic the situation is, and to identify them all you need to have as much information as several courses.


The naming and numbering of data transfer standards is such that it can be considered the most complex case in the USB world. USB-IF recommends logos and tags for three versions, including USB 2.0, USB 3.2, and the new USB 4.0 standard. USB 3.2, meanwhile, includes the older USB 3.1 standard.

But since most companies do not care to follow them, you still see some differences; Like USB 3.1, which is listed in the specifications of many new products, which should ideally be USB 3.2.

Data complexities do not end here. For example, USB 2.0 data transfer speeds on paper are 480 Mbps, but data in USB 2.0 can only flow in one direction, so you can actually have a maximum speed of 30 MB. When manufacturers refer to USB 3.2 without additional information, data transfer speeds can vary from 5 to 20 Gbps.

For a better understanding, take a look at the table below. If you can not remember this information, do not worry; Because no one can. Even the chairman and chief operating officer (COO) of the USB-IF Association has admitted that not all of this information is preserved.

This forum has tried to solve these problems in USB4 by offering only two speed standards of 20 and 40 Gbps. The association has decided to develop USB 4 based on Thunderbolt 3 technology. Intel introduced this interface in 2011, which is compatible with a variety of protocols and allows the transfer of data, images, etc. USB 4.0 will support 100-watt charging speeds, data rates of up to 40 Gbps, and enough bandwidth for two 4K monitors or a 5K monitor. Does not exist. In addition, this protocol is compatible exclusively with the USB-C connector. The main idea is that all the previous standards should be included in this connector so that the user can enjoy high data transfer rates, fast charging and fast and painless streaming of video and audio at the same time, but implementing this process is not so fast in practice. p>


USB-IF provides the standard USB-PD (Power Delivery) charging specifications used by companies such as Apple, Google and Samsung in their products. This guide helps companies design devices that safely offer fast charging capabilities to users by specifying power limitations and design methods.

This forum introduced new logos to display in September last year. He introduced the specifications of USB4, USB Type-C and USB Power Delivery cables and chargers, which indicate the power and speed of cable transfer and companies should engrave them on their products.

As you can see in the pictures below, the logos are very simple. And contain only one expression next to a number that indicates the maximum supported power. However, you have probably never encountered products that contain these logos. You should not forget that not all manufacturers follow this standard and many of them have their own method. For example it must meet charging standards Qualcomm fast charging, Oppo SuperVooc charging, OnePlus Warp charging and Vivo Flash charging mentioned in the smartphone world.

A conflict that only hurts the user

Now that we're somewhat familiar with the market turmoil, understand USB-IF efforts to establish simple, clear logos as Unit standard is easier. The president of the association says that the purpose of USB-IF is to make sure that all users can easily understand the capabilities of the USB-C cable or port by looking at the logo. It sounds simple, but the question is, who's going to force companies to do that?

The fact is that USB-IF is just a consulting firm. Although many companies are involved in compiling the association's guidelines, USB-IF is not in a position to force hardware brands to use logos on USB devices and accessories.

Each company pays an annual fee of $ 5,000. The dollar can join the organization. One of the benefits of joining this association is the right to vote and comment on changes that will be made to future standards. Apart from this, USB-IF issues certifications for cables and peripherals. Issuance of this certificate is free for members and non-members can certify their products through laboratories.

These companies must send their products for testing and certification before engraving the association's approval on their products. Have received. The main problem is that any company can implement USB without obtaining this certification, and even if it does, it does not have to use the logo.

Wide Differences in USB-C Cables Advise users to purchase USB-IF certified cables. He also emphasizes that it is still difficult to determine exactly which cable to buy and that users have no easy way to identify the capabilities of the cable they are buying.

What does the future look like?

USB -IF in the new USB 4 standard, has tried to integrate many things together. For example, it uses only USB-C connectors, is compatible with devices with USB 2.0 and USB 3.2 ports, and includes standards such as Thunderbolt 3.0

As Martin Worth says, USB 4 does not last long, it takes several years to see compatible gadgets and accessories on the market. But in the end, the USB 4 landscape looks great because it's a super cable that does it all. Do not have. So you still have to look at the specifications of different cables with a magnifying glass.

However, the USB-IF community does not intend to give up its logo-based solution. "The ultimate goal is for the logos to represent two important pieces of data for five different types of cables: data transfer rate and maximum supported charging power.

So, according to current specifications, there are five types of USB cables. There will be C to C: USB 2.0 (480 Mbps), 5 Gbps, 10 Gbps, 20 Gbps and 40 Gbps. All of these cables also have symbols that indicate their charging power.

This solution in theory Sounds great, but how does the association plan to implement it? To begin with, a mandatory USB-C tag is provided for products receiving USB-IF certification. However, since you do not need the approval of this organization to use USB, we will end up with a lot of asymptomatic cables, which does not seem like good news.

Finally, USB-C, no matter how On the other hand, due to this turmoil in the market, we have not been able to take full advantage of its potential. As reported, the iPhone will join the USB-C user community in a year or two. We hope the situation has improved a little by then.
