zero delay is impossible with USB

Explain.

Yeah obviously, but its a chink name and every seller names it "zero delay board"

>> No.1588852

>>1588849
I guess because USB doesn't perform a CPU interrupt like PS2? Kind of a stupid thing to say though, the polling interval on USB is tiny.

>> No.1588854

>>1588849
Well literally zero delay is of course physically impossible.

But let's say something reasonable like 0ms delay. That's already impossible. Since even USB 2.0 Full Speed only guarantees one polling per millisecond. So even the most expensive gaming gear has a max update rate of 1kHz.

USB 3.0 might be better, but I doubt it's a USB 3.0 device.

With anything lol

>>1588854
Or high speed of course
Thinking laterally iso endpoints move one packet per frame, multiple endpoints retorting the same data will be sub 1ms

Would these work with toggle switches? Does it have to be push button?

toggles are fine:

These boards work great for simple boxes - I use one for a IGN + starter panel.
