Computer freezes up when using USB 2.0

With this USB 2.0 adapter, my PC reliably freezes up after some arbitrary interval of time, causing me to have to hard shut up my PC each time. Also, it takes about 1.5 minutes for the screens to display after the PC is booted up and ready to go. I really want to love this product. But it’s frustrating me and I am about to return it to Amazon.
