I used to think USB cables were simple. If the connector fits into my device, then surely the cable would work the same as every other one that looked identical. That a**umption turned out to be completely wrong, and I only realized it after running into several frustrating problems with USB-C devices on my Windows 11 PC. One cable would charge my phone quickly, but transfer files slowly. Another worked perfectly with my external SSD, while a different cable caused random disconnects. I also had moments when a USB-C accessory refused to work properly, even though the cable fit physically without issue.
