Does someone have moherboards with Haswell+Lynxpoint? I have problems with USB. In Linux USB devices work fine with "ehci-pci" driver and don't work correctly with "ehci-hcd" driver (they freeze completely short time after boot). In Windows USB devices work fine in safe mode and don't work correctly with normal mode (again they freeze completely short time after boot).
What is the difference between these two Linux drivers and what can be the source of this problem?
