Im assuming the usbehci. Im having the same problem too, why is this happening? So on this cool forum no one seems to have the answer. Is there another way around? What if i install XP first then install SP2 would this make a difference if i was not to streamslip this together.

However, in many cases malware can also cause the corruption of software which can lead to BSoD error, so remember to perform regular scans to ensure that your computer is free from any suspicious malware or virus. The responsibilities of the xHCI driver include initializing MMIO registers and host memory-based data structures for xHCI controller hardware, mapping transfer requests from upper layer drivers to Transfer Request Blocks, and submitting the requests to the hardware.

After completing a transfer, the driver handles transfer completion events from the hardware and propagates the events up the driver stack. It also controls the xHCI controller device slots and endpoint contexts. The xHCI driver is new in Windows 8 and is not an extension of the eHCI miniport driver that was available in earlier versions of the operating system.

The new driver is extensible and is designed to support other types of host controller drivers that are expected to be developed in the future. The USB host controller extension serves as a common abstracted interface to the hub driver, provides a generic mechanism for queuing requests to the host controller driver, and overrides certain selected functions. The xHCI driver, when ready for processing, retrieves the request from the queue.

The responsibilities of the USB host controller extension driver are:. The new hub driver, in the USB driver stack for 3. The hub driver primarily performs these tasks:. Windows loads the hub driver as the FDO in the hub device stack.

Device enumeration and hub management in the new driver are implemented through a set of state machines. In addition to hub management, the hub driver also performs preliminary checks and processing of certain requests sent by the USB client driver layer. For instance, the hub driver parses a select-configuration request to determine which endpoints will be configured by the request. After parsing the information, the hub driver submits the request to the USB host controller extension or further processing.

The drivers in the USB 2. At the bottom of the USB driver stack is the host controller driver. It consists of the port driver, Usbport. When the system detects host controller hardware, it loads one of these miniport drivers. The miniport driver, after it is loaded, loads the port driver, Usbport. The port driver handles those aspects of the host controller driver's duties that are independent of the specific protocol. The Usbuhci. If the Step 1 fails to resolve the usbehci.
