What information could I send that would stimulate a response? Is this the right place to post my question? Perhaps I could simply ask for the brand and modelof an add-in USB controller that is known to work well with 5.3-RELEASE or STABLE. My current controller, with OPTi 82C861 chipset, does not work well. I am having trouble finding an add-in card with an Intel chipset. Any reply much appreciated.
