Endurance USB port

Question

Iron

The question of how many insertion / extraction operations are designed for USB ports is very worrisome. I ask because I have repeatedly encountered the fact that the port stops working due to the fact that either the contacts are worn out or the connector is loose.

Is there any way to extend the life of the USB port?
Google turned up nothing on this issue.

Answer 1

Page 108 of the USB 2.0 specification.
Test description: Durability
Performance requirement: 1500 insertion/extraction cycles at a maximum rate of 200 cycles per hour.
But this is a criterion for passing the test for compliance with the standard, and not the minimum requirements for the actual connector or port. But I did not find such requirements in the specification.

Answer 2

The problem is quite real - my USB ports deteriorated after a maximum of 2 years of intensive use. The solution turned out to be simple - I connected the USB cable as an “extension cable” and I inserted all the devices into this “extension cable”. Periodically I throw away these cables (Chinese junk for a couple of dollars) and buy new ones.

Answer 3

There is a more convenient option than an extension cable, namely USB-HUB, it has 4 ports at once, there are 6 and 8 port usb hubs. You just need to decide for which devices the hub is taken, if for connecting energy-intensive devices (external hard drive, scanner), then you need to take an active hub (with a power supply) for about 500-700 rubles, if just for flash drives, etc., then it will do passive for 250-350 rubles.

Answer 4

How do you imagine such calculations?
It all depends on how carefully you use it.
