Check if your USB cable is suitable for your PC's needs.
My phone doesn’t work with my computer via USB-C. I’m using a Samsung Galaxy S22+ and an MSI B760 Tomahawk WiFi with Intel 12700KF. The PC won’t let me use the USB-C to C cables on its rear MOBO port. After plugging in the phone, Windows starts a weird sound and Explorer opens with storage info. I click “Internal Storage,” then “Downloads.” The process stops and restarts several times. After waiting 30 seconds, the phone says it can transfer files. I try using the USB-C to C cables again—both work fine on my laptop. I’ve got a new C-to-C cable labeled SS20 and an older one labeled SS40. The newer ones are faster but still slow. I suspect the issue is with the port, cable, or motherboard setup. I thought it might be a driver problem, so I reinstalled drivers and updated everything. Still having trouble connecting files.
I recommend using a standard USB-A to USB-C cable since the S22 doesn't support very high speeds. It seems like there might be a hardware issue or a power management problem where the board tries to handle more than it should, triggering safety measures.
These claims might hold some truth, but is my approach really "a USB cable that’s perfect. Spend more money. The computer is fine. It should just prevent things it’s certified for?" I’m hoping to find faster USB-A cables and avoid this problem, though I shouldn’t expect a guarantee. My device has a USB SuperSpeed 20 GBPS port, but I shouldn’t rely on a trusted brand cable with identical certification.
It appears to be a simple USB power delivery issue. Regardless, based on what I found, it should work with a USB 5GB/s connection—any USB 3.0 cable should suffice. The frequent disconnections when using a high-speed cable with this Samsung device aren’t unusual.
If it doesn't work with my laptop, I'm probably to blame for choosing the wrong MOBO. Regardless, it's really frustrating when we purchase items that claim to be compatible but fail completely. Even a brief failure makes me think many people face the same problem, which only adds to the frustration. It feels like a waste of money and effort. Just spend wisely and get what you need.
And that explains why we see terms like "certifications" and "standards." It's simply a USB-C port—it's not meant for a passthrough GPU. I found a matching cable and connected it to a regular phone from the same era, just three months later! I'm not trying to force a Galaxy S24 onto my 2015 Z-87 board expecting PCIe Gen 5 performance. I have several items that are two years old, still functional and receiving updates, and I expect them to integrate smoothly. I'm genuinely shocked that people overlook this when they spend their time in tech. Cheap cables? Fine. New products that still need support? Yes. Cutting-edge tech like VR in 2016? Absolutely. But a phone paired with a desktop computer? That just shouldn't work.
I would simply rely on what functions correctly rather than worrying about intended behavior. Probably the situation involves a hardware problem with the rear USB-C port. If I had it, I’d look closely for bent or cracked contacts. You’d likely need to use magnification since these components are very small and hard to see. I’d also examine the phone’s port, though that seems less probable. Both USB-C and USB-A connectors should support data speeds similar to your device (USB 3.1 on the S22 is the standard?). Quality cables matter too, but PD features aren’t directly tied to transfer rates. Don’t assume saving a few cents means a poor product—this applies to any brand. Edit: it could also be another device plugged into the same USB bus, either too loose or too tight.
I thought of this, which is why I tested with other cables. It's a brand new MOBO and the pins inside are pristine (I checked using a tiny tube camera I have for ear canals). The phone has no issues whatsoever, even with the fast cables. I can use them on my laptop. This is the first time I've ever used the port. I also have no issues with my other cables in it, only the fast ones. I have tried removing all other USB cables except the mouse (which I moved to an empty port, just in case, and the issue persists. The only way it could be the port is if there's a totally unused pin that none of my other cables use that ONLY the new ones use, and even then, I'd think that it wouldn't connect fully, or just would run at a slower speed. It shouldn't disconnect entirely, then reconnect. If it's shorted/grounded out, then it shouldn't work. If it's not, then it should just run with the pins that are working. It can't work AND not work. Everything seems to be pointing to "cable too much for MOBO to handle because screw testing things to work at their full capacity."
