    Fault : Device Manager Code 43 -- "Windows has stopped this device"
    Fix   : Stop Windows suspending the USB port
    Source: https://jbtecwiz.com/support/win-hw-code43

    Run as     : Elevated PowerShell
    Expect     : 15 minutes
    Risk       : low
    Reversible : yes

    WHEN THIS IS THE RIGHT FIX
    A USB device, particularly one that fails after the machine has been
    idle or has slept.

    HOW TO UNDO IT
    powercfg with a value of 1 restores selective suspend; the checkboxes
    can be ticked back.

    This script walks the fix one step at a time and asks before each
    one. Steps with no command are things you do yourself -- it prints
    those and waits. Run with -DryRun to print without executing.
