RE: You have...

Changing the Polling frequency just changes the way the signals intermodulate.

And your evidence for the "just" bit is?

I ask because the link suggests that, despite being confused about what was involved (you muddled it with the very different gamers' trick of increasing HID polling rates), you supported the suggestion.

Note that the RegEdit change discussed lowers the rate at which USB ports are polled from 1KHz to 200Hz and is applied per controller. I see I suggested that:
. . . the default MS polling interval is one millisecond, i.e. its frequency is 1 KHz, bang in the middle of the mid-range. If the activity, esp with consumer-level DACs, exacerbates jitter even slightly, the effect of moving it to the less-sensitive 200 Hz region might well improve the sound.
It can also make your usb devices less responsive.

Sure. Drives take forever to copy, scanning slows to a crawl, the sky goes dark, cows starting herding beneath trees and there's an eerie silence.

Solution? Don't perform the change on controllers driving HDDs, scanners - or cows.

But I'd wager that neither you nor anyone else has ever spotted a performance difference. And were Rick do so, he might just have the gumption to reverse the change.

You're making this up as you go along.
