Its a fragile connector, which breaks easily. Not only that, its an expensive part to repair.

For one thing, its highly NON-standard connector.

Its call “universal”, yet there are so many mounting styles of usb connectors. Some have different leg placements. Some have a longer body than others. This means although the interface looks the same, the way it connects to the board is different. This means a repair shop will have to order several different styles to be able to fix a USB problem.

Also, it’s non standard because manufacturers can add components in order to activate the USB function. So, one particular device has a reisistor in the USB plug, and this is NOT compatible with plain USB connectors.

Visually, both USB connectors look the same (unless you open the cover). This can make troubleshooting USB connector problems very confusing, and such a tiny part is difficult to repair. I have fixed the resistor before, but I could have easily broke it. If I broke it, I would have to buy a new one (which is expensive to do).

Also, I did not break the USB connector, it came loose very quickly. I work in a repair shop, so I can fix it rather then send it back. Many customers are complaining about broken USB connectors after using their device normally, and the manufacturers are denying the repair under warranty claiming the customer broke it when it was poorly manufactured.

Now people believe its Standard, but there are so many variations in case styles and external resistors required. Even voltage difference, which further adds to confusion. People should just know what a connector looks like, associate it with that function, and it should work. With the voltage difference, this is not the case.

And, the USB connector standard will change. First mini-USB, then micro USB. So, compatible devices will be harder to find.
