Uninstall all usb devices from my device manager (I use the keyboard only to reinstall from a “fresh” system) Recently, I buy a new phone, still USB2, and I try to plug it in my front panel (internal USB3.0 headers Intel) and of course it didnt work (as usual ) Everytime I have to connect a USB2 device I go under my desk, take my frontal lamp and plug it in the n☁3 USB3 port I tried all the drivers from Asrock website since 2 years now, from Intel drivers, and many drivers website and abandonned at the end. All USB3 devices (microSD card reader, external HDD) work on all USB3 ports. I can’t read any USB2.0 devices (3 differents USB sticks and my phone Samsung GS3) on the different USB3.0 port except the rear USB3.0 port (n☁3 in rear panel).

I work with Asrock X99 Extreme6 work under Windows 7 圆4 (details below)
