      Description

      I try to use USB keyboard (Sven Multimedia El 4002) and mouse (Defender opera MB-800) on x86 hardware (with Intell P55 chipset). This devices does not work.
      When I try to pass through this devices under VirtualBox (with USB 2.0 EHCI controller selected) it works ok.
      I found some difference in debug log while driver initialization. On real hardware it have this output as addition to Vbox log:

      (drivers/usb/usbehci/hardware.cpp:267) Controller has Debug Port Support At Port 2
      (drivers/usb/usbehci/hardware.cpp:272) Controller has Extended Capabilities Support
      (drivers/usb/usbehci/hardware.cpp:287) Controller uses 64-Bit Addressing

      Under VBox it have only one different message:

      (drivers/usb/usbehci/hardware.cpp:277) Controller supports Asynchronous Schedule Park

      This message give me an idea assign m_Capabilities.HCCParams.ParkMode = 1 to force using the same mode on the hadware. This hack gives nothing.
