I have a Toshiba satellite a305d-s6848. The specs for this can be found here: reviews.cnet.com/laptops/toshiba-satellite-a305d-s6848/4507-3121_7-33088925.html (Sorry for no link, but I am apparently not allowed to do that yet. I bought it new and it came with windows vista. A couple years later I upgraded to windows 7. Upgrading to the new OS was fine, but then later I needed to upgrage yet again to 64 bit. This, unfortunately was not as easy and I need to wipe the drive clean and start fresh. Now there are a couple issues with the host controllers, the main being that I keep getting warnings saying that the devices I plug in can run faster if I were to use a high speed port (2.0). This confuses me because the USB ports are 2.0, but they are acting like they are 1.1. I have done everything I can think of to get these to function correctly, but nothing I do seems to work. The second issue (which isn't as annoying) is that when I move the screen, the sound for connect / disconnect a USB device is played and the little popup for "new device connected" is shown. I am unsure why the screen is acting like it's a USB device. I have disabled the notifications and sounds for all ports now, but I would kind of like to know why this is happening. Do anyone know how I can solve these problems? I have checked multiple forums, and have been searching for an answer for about 3 months now with no luck. I think I have provided enough information, but if anyone needs more, just let me know and I will be happy to provide it. Thanks.
