I've been using this cable for about a month with no problems. The cable is ideal for configuring Cisco devices. Unfortunately the cable no longer works today. It shows up briefly in Device Manager before the computer decides it's disabled. I tried to unplug the cable from the USB port and it was hot. I've tried this on multiple systems with the same result. This is very bad because it seems to be a really good quality cable. Be careful and have a spare console cable on hand just in case.
