Are your layers separate layers or grouped layers (i.e. layers=a,b,c)?
Would setting the layers property of the control work for you?
/**
* Property: layers
* {Array(<OpenLayers.Layer.WMS>)} The layers to query for feature info.
* If omitted, all map WMS layers with a url that matches this <url> or
* <layerUrls> will be considered.
*/
layers: null,
Best regards,
