Obviously the Renesas device won't work with the Intel xHCI drivers for Windows 7 and vice versa. Again there is no advantage over the default Intel chip emulation. Likewise the Renesas device emulation works with Windows 8 and later guests, as well as Linux etc. However, there is no advantage to using the Renesas drivers over the Intel drivers for Windows 7. The driver supports 32-bit and 64-bit versions of Windows XP, Vista (FTW!), and Windows 7, as well as the corresponding server versions. The extradata key also needs to be removed when switching to OHCI/EHCI. To go back to the default Intel chip, remove the extradata key. That can be set as follows:Ĭode: Select all Expand view Collapse view VBoxManage setextradata VBoxInternal/Devices/usb-xhci/0/Config/ChipType uPD720201 To enable the Renesas xHCI controller, a VM must have xHCI enabled and additionally needs a 'magic' extradata key. Note that the drivers must support the uPD720201/202 chip, not the older uPD720200 or uPD720200A. For example ' renesas usb driver 3.0.23.0' is a good search term. The good news is that the drivers aren't too difficult to find. Only OEMs get the drivers and provide them to their users.

Unfortunately, unlike Intel, Renesas does not offer any drivers for download. The key is emulating a Renesas (formerly NEC) uPD720201 xHCI controller instead of the default and better documented Intel Panther Point chip. VirtualBox 5.0.10 (or rather its Extension Pack) includes an experimental feature which allows Windows XP guests to use USB 3.0.
