There is a possibility that BSOD occurs when the xHCI Backwards Compatibility Tree is connected to USB 3.0 Host Controller and operating all devices and a setting of a ISO device application is changed on enabling the driver verifier.ġ-8. There is a possibility that BSOD occurs when the upper or lower filter driver is installed to USB 3.0 Host Controller driver and the xHCI Backwards Compatibility Tree is connected to USB 3.0 Host Controller.ġ-7.
We have never seen this issue on Windows Vista/7/Server2008R2.ġ-6. In order to solve this issue, we modified the host driver to set "HC BIOS Owned Semaphore" bit to '0b' forcibly if "HCHalted" bit of USBSTS register is '1b'.ġ-5.There is a possibility that BSOD occurs when users connect the xHCI Backwards Compatibility Tree to USB 3.0 Host Controller and operate all the devices in the xHCI Backwards Compatibility Tree and uninstall USB 3.0 Host Controller in Device Manager. If a system using SMIB signal doesn't set "SMI on OS Ownership Enable" to '1b' after S3/S4->Resume, there is a possibility that the host driver cannot obtain Ownership and Device Manage shows the yellow bang for USB 3.0 Host Controller. Therefore, BIOS needs to set "SMI on OS Ownership Enable" bit in USBLEGCTLSTS register to '1b' if BIOS has set "HC BIOS Owned Semaphore" to '1b' and hands Ownership off after S3/S4->Resume. There is a possibility that BSOD occurs when S3/S4->resume is executed with the xHCI Backwards Compatibility Tree on enabling the driver verifier.ġ-4.The host driver clears USBLEGCTLSTS register after the host driver obtained Ownership from Ver3.0.2.0Beta. There is a possibility that BSOD occurs when performing the Common Scenario Stress-with-IO test in WHQL, when connecting an external USB hub to USB 3.0 Host Controller.ġ-3.
When continuously starting & stopping the video capture with a specific USB2.0 Camera, the specific USB2.0 camera cannot restart the video capture.ġ-2. Additional remediation was implemented for the following issues:Ģ-2.
