 .PARAMETER MaxUSBDrives
 Maximum number of USB drives to build in parallel. Default is 5. Set to 0 to process all discovered drives (or all selected drives when USBDriveList or selection is used). Actual throttle will never exceed the number of drives discovered.
 
+.PARAMETER Threads
+Controls the throttle applied to parallel tasks inside the script. Default is 5, matching the UI Threads field, and applies to driver downloads invoked through Invoke-ParallelProcessing.
+
 .PARAMETER UserAgent
 User agent string to use when downloading files.
