Does exactly what it's supposed to. I have a media center in a closet and a TV in another room. I have an HDMI cable running through walls along with CAT5 for the USB signal. All 4 ports are recognized by Windows, but when I plug in a remote receiver, a keyboard/mouse combo receiver, and an Xbox 360 PC receiver, my desktop shuts down. I think that's because it can draw too much current from a single USB. Since I rarely use the xbox 360 receiver, I can get by with just two devices connected. The only problem I've found (by default I think) is that my keyboard and mouse combo isn't recognized at the BIOS level (because of the USB hub I think). I need to set the BIOS to ignore Windows and continue booting. On Windows everything works as usual. I used to have a passive USB 1.1 extender that kept disconnecting and reconnecting. This USB extender works very well and has not experienced any disconnection.
