I don’t know much about cables so if type something wrong forgive me …
I was wondering around with some old stuff, and found this cable that is usb to usb “as shown in the image below”

Now what i thought was that it might be used to connect 2 computers with each other so i tried that and connected 2 computers with each other using it and nothing happened Can anyone tell me what this cable is even used for ???
It’s not an officially sanctioned application of USB, but some product vendors use it for various reasons. After all, a USB cable is just a bunch of wires (some twisted together a special way).
One example that springs to mind is the HTC Vive link box. This was made before USBC was very popular, and I’m guessing they wanted USB 3 speeds with a lower profile connector. Typically, you’d use an A to B cable, but the B connector is much taller.
Thanks for the info, I have another question. Can it be used to connect one pc to another maybe for sharing files or for doing some other stuff ?
Generally no - USB connections are asymmetric, with hosts and devices. Your PCs are both hosts - they cannot function as devices or communicate with other hosts.

Nope. Computer USB A ports are “upstream ports.” Both computers would be expecting to find a downstream device on the port. USB needs a single host to control everything. Can’t have two hosts.
If it was already tried with this specific cable and it didn’t work, then this cable doesn’t have the capability built in. Some cables like this have a bridge in the cable that allows pc to pc communication.
Not without special support from the hardware and software. But a smartphone is pretty much a PC with specialized hardware and software. And you can certainly plug your smartphone into a PC to share photo’s.
I’ve used these while developing consumer electronics. One product had only a single USB port, and it acted in device mode during bootup for debugging purposes before switching to host mode so it could talk to peripheral devices.
I had a cable like this, it was for an ancient Medion digital camera. No idea why they went with the full size USB female socket on the device, but it was just a simple USB cable that had male plugs on each end. Maybe it was cheaper, maybe it had debug purposes… we will never know.
I also tried to connect two PCs with it, it was my very first thought when I saw that cable. Obviously, it didn’t work, nothing happened. Remember Total Commander had a “Connect two computers with USB” feature, was thinking maybe that will work with it, but nope… for that, a specialized USB cable/device was needed, not the one I had for the camera.
I use it for connecting a computer to a KVM
It was used to power the Vive Wireless Adapter. I’ve also seen a Steelseries keyboard which used this cable type.
It’s not widely used, but it’s nice to be able to buy one
I have some converters that are female A to male B/micro/mini for instance. This would be useful as an extension in that case.
Image isn’t working for me. Is it male-male? A lot of perepherals used to use those. If it’s female-male it’s just an extension.
Yes, its male-male
Well, I’ve seen this stupid USB cable before. I think it was external HDD on AliExpress.
Yep, I have an external IDE/SATA reader that uses one of these cables.
I use a cable like that to link two Car dvd players that are in the back seat. One’s the player with the disc in it and the other is just a viewer, both hang from the front seat head-rests.
That’s how you kill a USB port 101
Why would it kill the port? I think the power lines would be at equal voltages on both ends and the data lines just wouldn’t do anything.
Not exactly equal. One will try to feed to another which can kill it. It’s not made to be connected like this. Maybe they could even fight if it tries to compensate by increasing voltage.
But hopefully there’s some protection that disables the USB port before something ugly happens.
This is entirely dependent on how the circuitry is set up. However USB voltage is always 5 volts and the controller doesn‘t go over that.
Do you mean that it was risky connecting one pc to another with this usb to usb cable ???
