VirtualBox (4.3.6)

  • VirtualBox emulates two USB host controllers, EHCI and OHCI. There is a need for two host controllers because OHCI only handles USB low- and full-speed devices (both USB 1.x and 2.0), while EHCI only handles high-speed devices (USB 2.0 only). The emulated USB controllers do not communicate directly with devices on the host but rather with a virtual USB layer which abstracts the USB protocol and allows the use of remote USB devices.
