Hi, great video! I'm trying to understand why certain cables do or do not support high transfer speeds or fast charging. Is that hardware or software related? E.g. do cables with slower data transfer have less physical wires in them (so not all 24 pins are active and thus less lanes are available) or does it have something to do with the cable's configuration settiings (the config pin pair)?

Thank you for your compliment! Cable performance, in terms of data transfer speeds and support for fast charging, is primarily determined by its physical characteristics, including the number and quality of wires and the cable's configuration. It's more of a hardware-related factor rather than a software one. Here's how it works: Number of Wires/Pins: The number of pins or wires in a cable can significantly impact its capabilities. For example: USB cables typically have four wires for basic functionality (power, ground, and data). USB 3.0/3.1 cables have additional wires for faster data transfer. For example, USB 3.0 has nine pins, while USB 3.1 has 24 pins. High-quality USB-C cables often have even more pins to support features like fast charging, video output, and data transfer. Wire Quality and Material: The quality and material of the wires matter. Higher-quality cables often use thicker wires with better conductivity. Thicker wires can carry more current, which is essential for fast charging. Fast Charging: For fast charging, both the charger (power source) and the device being charged (e.g., smartphone) must support fast-charging protocols like Qualcomm Quick Charge, USB Power Delivery (PD), or others. Additionally, the cable must be capable of carrying the higher current needed for fast charging without overheating or voltage drop.
