According to the USB 3.2 specification, it states that USB 3.2 Gen 2×2 can support a SuperSpeed Type-A connector. This raises a question:

If we use a SuperSpeed Type-A connector, the system would only utilize 1 lane for data transfer, leaving 1 lane from the host unused. Is this configuration valid,...

Hi everyone,

I'm a hardware engineer with a background in high-speed PCB design, power electronics, and embedded systems. Outside of work, I spend a lot of time reverse engineering and repairing laptop motherboards—something I'm really passionate about.

I have experience with power rails, DC-DC converters, VRMs, MOSFET drivers, and general fault tracing on modern laptop boards. I'm also familiar with boardviews, schematics, and oscilloscope/multimeter diagnostics.

I joined this forum to both learn from experienced members and contribute where I can. I...
