In general, if you don't use dual boot, this may not be a problem. You have to use it to enter GRUB or BIOS configuration, well that rarely works. I have a wired keyboard and it still doesn't work. When I get a POST, I see the keyboard LEDs come on and then go off again. This shows that the keyboard is not getting power, so I can't use my keys to change my OS in GRUB or BIOS configuration. This works about 10% of the time. The BIOS is set to full USB support and is waiting until properly powered. Even without this product, it works great even with a USB hub in the way. I found that I can exit BIOS configuration and GRUB works. It helped me, but I can't leave this product for that.
