Also, a picture helps a lot if you have one.\n\nHere are some possibilities of what a \u201cUSB connection with two little dots\u201d could mean:\n\n---\n\n## \ud83d\udd0c Possible meanings\n\n1. **Securing holes on USB-Type A plugs/ports**  \n   On standard USB-A connectors (the rectangular kind), there are often *two small square holes* on the top side of the **plug** (or matching tabs in the **port**). These don't change what kind of USB it is\u2014they help the plug click securely into the port so it doesn\u2019t wiggle loose. ([pocket-lint.com](https://www.pocket-lint.com/usb-type-a-square-holes/?utm_source=openai))\n\n2. **Symbol-icons printed beside USB ports**  \n   Sometimes, little symbols or icons next to USB ports have extra markings like \u201cSS,\u201d lightning bolts, or little shapes. These indicate speed, charging ability, or other features. For example, \u201cSS\u201d means SuperSpeed (USB 3.x) for faster data transfer. ([geekinter.com](https://geekinter.com/what-do-the-symbols-on-the-usb-ports-mean/?utm_source=openai))\n\n3. **D-shaped icon (DisplayPort symbol)**  \n   On USB-C ports, you might see a small \u201cD\u201d or D-shape icon printed nearby. That usually means the port supports **DisplayPort alternate mode**\u2014it can handle video output over USB-C. ([howtogeek.com](https://www.howtogeek.com/303561/what-does-the-d-shaped-icon-next-to-my-usb-c-port-mean/?utm_source=openai))\n\n---\n\nIf you tell me exactly where you saw the dots (plug, port, logo nearby, etc.) or send a photo, I can pinpoint exactly what it is."

([pocket-lint.com](https://www.pocket-lint.com/usb-type-a-square-holes/?utm_source=openai))\n\n---\n\n## \u2714 What\u2019s their purpose?\n\n1. **Secure connection**  \n   Inside the **female port**, there are small spring-loaded tabs that snap into these holes when you insert the plug. This helps grip the plug firmly and prevents it from falling out too easily. ([pocket-lint.com](https://www.pocket-lint.com/usb-type-a-square-holes/?utm_source=openai))\n\n2. **Correct orientation hint**  \n   Since standard USB-A is not reversible, the holes help you figure out which side is \u201cup.\u201d Usually, the side with the visible enclosed square holes is facing upward (for horizontal ports). ([pocket-lint.com](https://www.pocket-lint.com/usb-type-a-square-holes/?utm_source=openai))\n\n3. **Part of manufacturing & stability**  \n   Springs inside the port engage with those holes; they\u2019re part of the design that keeps everything stable both physically and electrically. ([electronics.stackexchange.com](https://electronics.stackexchange.com/questions/648273/why-do-usb-connectors-have-2-square-holes?utm_source=openai))\n\n---\n\nIf you tell me whether the holes are square or round, how many, and if there are any other markings (like a USB logo), I can help you confirm it's a USB-A plug\u2014or show you a picture for reference."

([pocket-lint.com](https://www.pocket-lint.com/usb-type-a-square-holes/?utm_source=openai))\n\nHere\u2019s a breakdown of what you're likely seeing and what it might be:\n\n---\n\n## \ud83d\udd0d Why USB-A plugs usually have *square* holes\n\n- The standard USB-A male plug often includes two small **square cutouts** on the top or sides. These engage with spring clips inside the USB-A port to help the connection grip and stay put. ([pocket-lint.com](https://www.pocket-lint.com/usb-type-a-square-holes/?utm_source=openai))  \n- These square holes are designed specifically for that mechanical latch action. ([electronics.stackexchange.com](https://electronics.stackexchange.com/questions/648273/why-do-usb-connectors-have-2-square-holes?utm_source=openai))\n\n---\n\n## \u2753 What if they're *round* instead\n\nIf the holes are round, possibilities include:\n\n1. **A non-USB version**: You could have a legacy or specialized connector that looks like USB but isn\u2019t USB-A.  \n2. **A modified USB plug**: Less likely unless someone cut or altered it. Standard USB-A plugs are manufactured with square cutouts.  \n3. **USB-B or Mini/Micro types**: Those sometimes have different shapes for connections or slots \u2014 but round holes on the *metal shell* are still uncommon.  \n4. **Something like a \u201clocking\u201d USB connector**: Some rugged or industrial USB connectors might use round openings or screw locks instead of the typical clips.  \n\n---\n\nIf you want, I can try to identify exactly what connector it is if you can tell me a few more details:\n\n- Rough plug shape (flat and rectangular? square? something else?)  \n- Size \u2014 how wide or thick?  \n- What device does it connect to (computer, camera, something else)?  \n- Any other markings (letters, logos, shapes)?  \n\nIf you have a photo, that'd help even more."
