Amd Usb 3.0 Extensible Host Controller - 1.0 (microsoft) Driver Download

I have a MSI laptop with an external USB keyboard and a mouse connected to it. This device controller, "Intel(R) USB 3.0 eXtensible Host Controller - 1.0 (Microsoft)", wakes up my PC from sleep. I have installed the latest driver for that and I have tried several methods to solve this but to no avail, including:

AMD has failed to provide a standalone installer, bundling the xHCIO driver with their sata controller drivers. You'll have to determine whether you (likely) have a 700 chipset series based system, or something else:

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

USB 3.0 introduces a new operating speed called SuperSpeed. Compared to USB 2.0 bandwidth of 480 Mbps, SuperSpeed supports 5.0 Gbps making it 10 times faster than USB 2.0. USB 3.0 also supports lower operating speeds: high speed, full speed, and low speed. Along with increased bandwidth, USB 3.0 host controllers and devices come with the promise of compatibility. USB 3.0 controllers are required to work with all existing USB devices. The fact that current PCs ship with both USB 2.0 and USB 3.0 ports presents an interesting challenge: how should you determine whether a USB 3.0 device is indeed operating at SuperSpeed?

Next, confirm that Windows enumerated the host controller as a USB 3.0 controller. To confirm that, open Device Manager and locate the controller under the Universal Serial Bus controllers node. If Windows recognized it as a USB 3.0 controller, USB 3.0 eXtensible Host Controller is appended to the device description as shown in Figure 6.

This article describes an issue that occurs when you transfer large amounts of data between Windows 8.1 and devices that are attached with certain USB host controllers. You can fix this issue by using the update in this article. Before you install this update, see the Prerequisites section.

I've struggled for many years with the Renesas USB 3.0 eXtensible Host Controller disconnects on two older Toshiba laptops. Because these laptops have a single USB 3.0 port these Renesas Extensible Host Controller issues have prevented the ability to use more than one USB 3.0 external hard drive no matter what USB 3.0 hub was used (various brands, both powered and unpowered). I'd plug in a second USB 3.0 hard drive (various brands, powered or unpowered) and if the drive was recognized by the Renesas controller, Renesas USB driver would shortly there after hang, freezing the USB 3.0 port, and disconnect all USB 3.0 devices. Only way to recover was disconnect the second or additional external hard drives and devices and reboot the laptop(s). Spend years trying to find ways around this issue, ended up having to put second and additional external hard drives on the USB 2.0 ports.

An update after some time running the newer Windows 10 Update optional drivers. Still getting occasional Renesas USB 3.0 eXtensible Host Controller errors/crashes where it disconnects all connected USB 3.0 devices. Not as often as prior to the optional driver update where it happened all the time, but still getting them. Its mostly confined to happening after the computer comes out of sleep/hibernation now. Its hit or miss. The controller will continue to work for a while then randomly crash requiring a computer restart to fix it. Better than before but still darn frustrating. Its like the Rensas controller doesn't like more than one USB 3.0 device (particularly USB 3.0 external hard drives) connected at any one time.

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.

Where possible, the drivers applicable to each device or classof devices is listed. If the driver in question has a manual pagein the FreeBSD base distribution (most should), it is referencedhere. Information on specific models of supported devices,controllers, etc. can be found in the manual pages.

These systems also contain Integrated Raid Mirroring andIntegrated Raid Mirroring Enhanced which this driver also supports.The SAS controller chips are also present on many new AMD/Opteronbased systems, like the Sun 4100. Note that this controller candrive both SAS and SATA drives or a mix of them at the same time.The Integrated Raid Mirroring available for these controllers ispoorly supported at best. The Fibre Channel controller chipset aresupported by a broad variety of speeds and systems. The Apple FibreChannel HBA is in fact the FC949ES card. This driver also supportstarget mode for Fibre Channel cards. This support may be enabled bysetting the desired role of the core via the LSI Logic firmwareutility that establishes what roles the card can take on - noseparate compilation is required. ff782bc1db
