I probably shouldn't admit this publicly, but I once spent several days
tearing my hair out over some complex USB interface code I'd written
(code that static analysis and runtime debugging on the embedded MCU
consistently showed was error free) before finally discovering that I
was using a "charging only" USB cable without any data lines.
Those d*mn things should be made illegal. And I didn't have PulseView or
any analyzer hardware at the time. Two lessons learned at once.

Thank you very much, I would have been chasing my tail forever.
