Servicing serial through USB has never been a picnic. This device installed smoothly and then mapped itself to COM9. My Garmin GPS only deals with ports COM1 through COM4, and I'm not interested in trying to update its firmware to see if it will deal with higher ports. The Keyspan user manual offered a large, unwieldy process for forcing it to service other ports - but I didn't want to deal with collisions with other devices and software. So I put it on the shelf and got a Trendnet, which worked right out of the box.
