Hello, Elena. Your father requested this adapter in 2020. We told him it was a prototype—a driver-level backdoor into legacy Windows kernels. He paid $500 for it. He never told you why. But he did leave a message.
Its legacy is defined not by raw throughput but by the community-driven driver support that bridged a gap between proprietary hardware and open-source operating systems. If you still own one, keep it as a debugging tool. If you are buying new, respect its limits: treat it as a 100 Mbps adapter, not a 150 Mbps one.
It is in the first 512 bytes of the adapter's firmware. He made us promise not to deliver it until the device had been "factory reset by hand."
