I use windows 8. Recently I have bought an external hard disk[toshiba] with USB 3.0 support. I have one port in my laptop with USB 3.0. My every hardware drivers are up to date[Including my BIOS]. The problem is when i connect hdd to 3.0 port, what i get is 2.0. [There's a light that show up white colour if it's 2.0 and blue if it's 3.0]. I have google-ed this issue many times and i did not get a solution that works for me. Now this is the part i don't understand. I do get blue light when i connect hdd to my 3.0 port and restart my pc. After that it becomes blue light and show installing device[only for the first time i got 3.0. Installed to Devices and Printers]. I could take off and plug in my USB at that time and get the speed of 3.0. But after another restart[or shutdown], it goes back to 2.0. Now my HDD is installed in Devices and Printers. There, its written in my status of my USB HDD that it could run a lot faster if it's connected to USB 3.0. After another restart I might get 3.0 again but now always. What i understand from this is my usb port that supports 3.0 don't recognize the port as 3.0 sometimes [not always] and uses my USB HDD as 2.0. In my other PC, i could connect my USB HDD whenever i want and get 3.0, so it's not a problem with USB HDD. I think some services in windows or some stuff needs to work to detect my port as one that supports 3.0. But i have no idea what to do. That's where i need help or if I'm wrong, please correct me. Thank you.
