Have you never just wanted to plug 2 PCs into each other back to back?
If you think about it, this is the USB equivalent of a double ended dildo
does this mean there's also double ended flesh lights?
Isn't that the nickname of your mum?
It turn@ a usb extension cable into a regular usb
I guess that could be a use case?
Or turn 2 extension cords into a long one.
But a serious answer is that these are sometimes sold in a kit of adapters that would let you change the head. Most kits like used a normal cord as the base cord, but some used USB extension cords as the base cord. So this is meant to be a replacement part, not useful in its own right.
wouldn't that just make this thing longer? we'd still have the same problem
There are female-female USB extension cables. As to why those exist...
They are good for wifi/bt/radio usb receivers used for keyboard/mouse/gamepads...so they can be in a better place like higher or further.
Such A-to-A adaptors and cables always have been prohibited by the USB spec, but people built them anyway. A common usecase for "illegal" A-A cables i remember was connecting PCIe cards (especially GPUs and mining cards) externally to riser sockets.
I have an external 3,5“ HDD enclosure that needs a male to male USB 3.0 A cable to plug into a PC. Still wondering, why they didn’t use B…
I’ve used them for extension, as it allows you to attach a second, regular USB cable to it.
Well, what do you mean by "regular"? The cable would need to be female on at least one end, which I usually see in... USB extension cables.
Not that you probably need to know this, but for some other stranger: there's a max functional length to USB cables. At work I remember pulling my hair out troubleshooting a printer until we swapped cables for something shorter.
And that max length goes down with each coupling.
We have smart boards in most classrooms, but in an entire wing of my department the smart board doesn't work. Reason? When we built the wing, 8 or 10 years ago, the installers fitted their own low grade plugs on the USB connection for the boards, before figuring out that they snipped the cables too short. Instead of running new cabling the installers then introduced another extension.
Nobody cared to check it out before accepting delivery and my complaints went unheard by management, until it was too late to RMA it.
Sometimes you have a female to female cable.
You ever watch Requiem For A Dream?
ASSSSSSS TO ASSSSSSSS
LUSBian sex obviously!
I dunno but it bothers me how much plastic wrapping that fucking thing apparently needs.
To connect two USB-A ports.
Basically the same as a USB-A to USB-A cable, just really short.
USB-A to USB-A cables do not exist, the USB standard does not allow them, if you have a cable with two USB-A connectors then it’s not actually a certified USB cable. The same goes for USB extension cables and this adapter. Note how there isn’t a ‘USB certified’ logo on the package.
USB-A to USB-A cables do not exist
wtf are you talking about, of course they do.
Show me where in the USB standards these are specified.
This is like saying that a building isn't a building if it's not up to code
They cables and exist and they work. So being "specified" doesn't mean jack shit.
The cables exist; they just don't follow the standard. I've used them when developing consumer electronics: the host controller on the device switches to device mode in the bootloader, allowing a host machine to connect and debug/flash the device.
I used to have a portable hard drive that had a usb-A/ e-sata hybrid connector and I had to use a USB A to A cable (or e-data) to use it.
It's an Usb-A gender changer. It's not that useful but you could use it to turn an otg adapter (female usb-a to male usb-c) into a regular usb-c cable. I'd rather buy a usb-c cable though.
I actually have a APC UPS at work that uses a USB-A to USB-A cable. You can look up the cable online, it's part number 940-0504. I was surprised APC used such a cable. I think if you tried to do something dumb like connect two PCs together with it, one of the USB ports would fry.
Many cheapo sata connectors need a cable like this(I use a male A to female micro b and then a female micro b to male A, it gets the job done)
But connector, idk
Causing fires
The way these are called male and female has always been so wild
It‘s a pretty good metaphor I‘d say and less bland than calling them plug and socket.
I would definitely find a couple use cases for these
Not one that short but I do have A to A cord like that in use. In my case it's with a KVM that I lost and AC adapter for but found that if I plugged in to one of the rear console connections it could get it to power on from the USB device. Cable it to a USB charging port on the front of one of the UPS and away it goes.
