Laptop USB don't works after installation (no pendrive, no mouse)

[Luca Serafini 0]

Sorry for English, but it is not my native language ..I installed it in an HP laptop. The SO starts with no problems and it works graphics, Audio, ethernet, keyboard and trackpad.The 2 problems are:1) just after the startup screen (the one Niresh), the apple logo is moved to the left and to the right you can see part of the screen Niresh. I'm not complaining of course. ;)2) Do not operate the USB ports: will not recognize the pendrive and not even a mouse. :(There is a system in order to solve the problem of USB? I tried with "USBBusFix=Yes" but nothing changes ... :unsure:Thank you very much
