Having an urgent need for a USB to RS-232 DB9 adapter, the helpful Best Buy folks quickly found this easy to install and use one at my favorite go-to place for electronics, accessories and so much more. There was no delay waiting for drivers to install, nor any problems operating with the devices connected to it. Thanks Insignia and Best Buy!!
