[BUG] v0.7.9 LEDs may occasionally flicker in any mode if `USB Host` is enabled and a device is connected

[TheTrainGoes]

Expected Behavior

LED animations are not affected by a device being connected when USB Host is enabled.

Current Behavior

When USB Host is enabled and any device is connected the LEDs may flicker in any mode every few moments.

Context

This has been tested on v0.7.9 from the release section.

When enabling USB Host and connecting any device (a USB mouse dongle used to test) there will be a flicker in the LEDs every few moments.

This was tested across all modes. For example, I have verified that the issue is present in Switch mode when a dongle is connected despite Switch not needing USB Host for anything. Removing the dongle will stop the issue from occurring.
