How many others have already written, the driver of an external source is not working. The SitePoint driver does work quite well, but there is (caused by errors in the driver) when controlling the COM port with PuTTY reproducible Bluscreens. Have found this on two different PCs. Furthermore, the device has begun with me for less than a year in operation, bringing the stream mess. Parts of the communication were missing or were simply overwritten. That was the point at which I gave the part to e-waste. A serial Slotblech - connected directly to the motherboard - performed significantly better job. Unfortunately BIGtec seems (or is that stuff ever shopped and relabeled by whom) to have no interest in improving the product or the driver. Hands off.
