Expected Behavior

10K potentiometer connected to analog I/O pin26 to dial the turbo speed

Current Behavior

So i tested the use of a Turbo button, a Turbo LED and a Turbo Dial function back in September 2023 on firmware version V.0.7.1 with a simple bread board.
Everything was fine and working as expected so i made a custom PCB.
Now i just assembled the PCB and flashed the new WaveshareZero firmware v0.7.7.
The Turbo functions are still working as expected but Windows very often fail to properly recognize the device, giving the "unknown device" error.
This problem goes away as soon i disable the Turbo Dial on pin26 in the web-config.
On top of that, if i plug the USB while the potentiometer is set to full turbo speed the configuration made in the web interface are wiped to the default settings.
If i load the old v.0.7.1 firmware on my PCB the problem disappear.

Steps to Reproduce

Please provide detailed steps for reproducing the issue.

1. Just enabling the Turbo Dial on an analog I/O pin make the device pretty unstable, Win11 and Win10 often fail to recognize the device

Start by reproducing the issue on an RP2040-Zero with firmware v0.7.7, a 10K potentiometer on analog pin26, and Turbo Dial enabled. Compare behavior with v0.7.1, focusing on Windows device recognition and whether web configuration resets when the potentiometer is at full speed. Done means Turbo Dial no longer causes USB instability or configuration loss.
