Hello, I have an Acer TimelineU M5-48-TG-6814 ultra book laptop. It has two USB 3.0 ports, but I recently discovered that there is something wrong with the drivers for them, because I can't use USB 3.0 devices at superspeed. I have plugged in 2 devices, and they both operate at USB 2.0 speed. In my device manager, I have several things under universal serial bus controllers:
4 entries for generic USB hub (I think that's my USB 2.0 hub)
2 entries for Intel(R) 7 series/C216 chipset family USB enhanced host controller
1 entry for Intel(R) USB 3.0 extensible host controller
1 entry for Intel(R) USB 3.0 root hub
2 entries for USB composite device
2 entries for USB root hub
I was having problems with my laptop, and recently reinstalled my operating system, with some resulting driver problems ( for some reason it didn't install with like any of the correct drivers, including the ethernet and Wi-Fi drivers, which were a pain in the **** to fix). This may be because the laptop originally came with Windows 7 home premium and I installed Windows 7 professional. But either way, I had to manually install lot of the drivers (I downloaded them from the Acer website), including the 2 entries for USB 3.0 drivers.
Anyway, although these USB 3.0 drivers say they are functioning correctly, they aren't. When I plug in my USB 3.0 devices, I can see that they are using the USB 2.0 drivers (I downloaded some software to see this: USBlyzer). I tried disabling the 2 USB 2.0 drivers ( the ones that say enhanced), then plugged in my device and it acted like nothing was plugged in. Also, I'm a little bit confused as to why there is only one USB 3.0 host controller and root hub entry, because I have 2 ports.
Anyone have any advice?
