Hi, I finally installed iATKOS M on my laptop(HP Pro Book 4520s) and everything are ok except from usb port and card reader.

 

When i boot with "-x -v" flags in safe boot everything works (4 usb ports and card reader) and when i normal boot into Mavericks only one usb port works... do you have any idea?
