Download Usb 3.0 Driver Intel Usb 3.0 Extensible Host Controller

When I right clicked uninstalled the Intel usb 3.0 extensible host controller, I lost all mouse and keyboard access and had to safe boot and revert to last know working settings (I still cannot use USB 2.0 at all). I'm concerned that I my uninstall one of the drivers and lost access to the keyboard and mouse forever - no ability to lose use the keyboard in safe mode.

Also, I'm now receiving the "Power surge on hub port" error message again. Previously I had never, ever received this message until I installed the USB 3 extensible host controller driver. Since I have no USB 2 right now, I can't plug the keyboard/mouse into the usb 2 and until/reinstall the USB 3 drivers.

I've tried to uninstall the Intel USB 3.0 extensible host controller driver. Re-installation of the latest driver from Intel failed and I got a BSOD during the installation. I updated my BIOS with the latest firmware from HP and the BSOD ceased but the driver still wouldn't install properly. I get an installation error and after restarting the USB 3.0 controller is installed but not USB 3.0 Hub which shows to be an Unknown Device. The driver installation log reveals the details below.

You need to update that PCI bus driver. That's the driver for the USB3PCIe bridge controller, and if it says the one already installed is newer, then it's likely a mismatched version to the XHCI and root hub drivers.

First: i do not know if there might be a bug/feature limit on your USB host controller or spec limitation (in case of devices, hubs in row) change in USB2 vs USB3 (Davids Answer seems to show the limit of the intel controller)

We solved the same problem by putting in an internal self-powered usb 3.0 4-Port PCI-Express Add-on Card. But only if your computer has the PCIe expansion slot. This adds additional host controller as the Intel one has reached its limit.

I debugged with v.marolda and it ended up being the Intel USB 3.1 controller wants to be called HCD1. Its a bug in their driver. I couldnt find any way to alert intel to a bug via email without joining some technical support program. So i hope they just fix it as it will conflict with other normal hardware host controllers.

On boot virtualhere searches for a spare host controller name. HCD0 is taken by the root host controller, so HCD1 is usually available and virtualhere driver calls itself that. However sometimes there is a race condition with another driver and so virtualhere will take the next number HCD2.

However the intel driver doesnt do this, it just fails if HCD1 is taken. Whereas really it should fall back to taking the next name e.g HCD2 or HCD3 but it doesnt and thats the "Object name already exists " error

The eXtensible Host Controller Interface (xHCI) is a technical specification that provides a detailed framework for the functioning of a computer's host controller for Universal Serial Bus (USB). Known alternately as the USB 3.0 host controller specification, xHCI is designed to be backward compatible, supporting a wide range of USB devices from older USB 1.x to the more recent USB 3.x versions.

The xHCI is a radical break from the previous generations of USB host controller interface architectures (i.e. the Open Host Controller Interface (OHCI), the Universal Host Controller Interface (UHCI), and the Enhanced Host Controller Interface (EHCI)) on many counts.Following are the key goals of the xHCI architecture:

When USB was originally developed in 1995, it was targeted at desktop platforms to stem the proliferation of connectors that were appearing on PCs, e.g. PS/2, serial port, parallel port, game port, etc., and host power consumption was not an important consideration at the time. Since then, mobile platforms have become the platform of choice, and their batteries have made power consumption a key consideration. The architectures of the legacy USB host controllers (OHCI, UHCI, and EHCI) were very similar in that the "schedule" for the transactions to be performed on the USB were built by software in host memory, and the host controller hardware would continuously read the schedules to determine what transactions needed to be driven on the USB, and when, even if no data was moved. Additionally, in the case of reads from the device, the device was polled each schedule interval, even if there was no data to read.

Legacy USB host-controller architectures exhibit some serious shortcomings when applied to virtualized environments. Legacy USB host-controller interfaces define a relatively simple hardware data-pump; where critical state related to overall bus-management (bandwidth allocation, address assignment, etc.) resides in the software of the host-controller driver (HCD). Trying to apply the standard hardware IO virtualization technique - replicating I/O interface registers - to the legacy USB host controller interface is problematic because critical state that must be managed across virtual machines (VMs) is not available to hardware. The xHCI architecture moves the control of this critical state into hardware, enabling USB resource management across VMs. The xHCI virtualization features also provide for:

The EHCI utilizes OHCI or UHCI controllers as "companion controllers", where USB 2 devices are managed through the EHCI stack, and the port logic of the EHCI allows a low-speed or full-speed USB device to be routed to a port of a "companion" UHCI or OHCI controller, where the low-speed or full-speed USB devices are managed through the respective UHCI or OHCI stack. For example, a USB 2 PCIe host controller card that presents 4 USB "Standard A" connectors typically presents one 4-port EHCI and two 2-port OHCI controllers to system software. When a high-speed USB device is attached to any of the 4 connectors, the device is managed through one of the 4 root hub ports of the EHCI controller. If a low-speed or full-speed USB device is attached to connectors 1 or 2, it will be routed to the root hub ports of one of the OHCI controllers for management, and low-speed and full-speed USB devices attached to connectors 3 or 4 will be routed to the root hub ports of the other OHCI controller. The EHCI dependence on separate host controllers for high-speed USB devices and the group of low-speed and full-speed USB devices results in complex interactions and dependencies between the EHCI and OHCI/UHCI drivers.

Support for Streams was added to the USB 3.0 SuperSpeed specification, primarily to enable high performance storage operations over USB. Classically there has been a 1:1 relationship between a USB endpoint and a buffer in system memory, and the host controller solely responsible for directing all data transfers. Streams changed this paradigm by providing a 1-to-many "endpoint to buffer" association, and allowing the device to direct the host controller as to which buffer to move. The USB data transfers associated with a USB Stream endpoint are scheduled by the xHCI the same as any other bulk endpoint is, however the data buffer associated with a transfer is determined by the device.

The EHCI specification was defined by Intel to support USB 2.0 devices. The EHCI architecture was modeled after the UHCI and OHCI controllers, which required software to build the USB transaction schedules in memory, and to manage bandwidth and address allocation. To eliminate a redundant industry effort of defining an open version of a USB 2.0 host controller interface, Intel made the EHCI specification available to the industry with no licensing fees.

xHCI 1.0 controllers have been shipping since December 2009. Linux kernels since 2009 contain xHCI drivers,[4] but for older kernels there are drivers available online. Windows drivers for XP, Vista, and Windows 7 are available from the respective xHCI vendors. xHCI drivers for embedded system are available from MCCI, Jungo, and other software vendors. xHCI IP blocks are also available from several vendors for customization in SOC environments. xHCI 1.1 controllers and devices began shipping in 2015.

Well the story is that I was trying to get Windows 7 to detect my arcade stick, but it keeps popping up and saying that the arcade stick is an Unknown Device. So one of the solution is to install the USB Intel 3.0 eXtensible Host Controller, but I forgot to do a step where I have to unblock the .rar that it came from. It didn't solve my arcade stick problem and another problem popped up, which is when Windows will keep asking me if I want to run the .exe for the host controller, which is not trusted everytime I boot the computer. So yeah to solve that inconvenience, I had to uninstall the host controller to later reinstall it back, but I had to restart the computer to reinstall it and tadaaaaaaaa.

0x07b usually indicates a problem with the SATA mass storage controller driver. I'm not sure where you downloaded the USB 3 controller from but they do not normally come in a rar format. Did you download the USB 3 controller from your MBs support site?

The Oracle Solaris 10 1/13 release supports the USB 3.0 specification. A newUSB host controller driver, xhci, is integrated in Oracle Solaris. Mass storagedevices and the USB hub that support USB 3.0 can both work inthe USB 3.0 mode when they are connected with eXtensible host controller interface (xHCI)ports. All the other legacy USB devices other than the USB audio andvideo devices continue to work when they are connected to xHCI ports. ff782bc1db
