Renesas Electronics uPD720201 / uPD720202 USB 3.0 Driver 220.127.116.11
[1. Modified driver]
1-1. Additional remediation was implemented for the following issues:
[ver 18.104.22.168's history, item 2-2]
2-2. When continuously starting & stopping the video capture with a specific USB2.0 Camera, the specific USB2.0 camera cannot restart the video capture.
1-2. 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.
1-3. There is a possibility that BSOD occurs when S3/S4->resume is executed with the xHCI Backwards Compatibility Tree on enabling the driver verifier.
1-4.The host driver clears USBLEGCTLSTS register after the host driver obtained Ownership from Ver22.214.171.124Beta. 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. 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. 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'.
1-5.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.
This issue only occurs on Windows XP. We have never seen this issue on Windows Vista/7/Server2008R2.
1-6. 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.
1-7. 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.
1-8. A specific USB 3.0 Flash device isn't detected when a specific USB 3.0 Hub, which has the USB 3.0 Flash device connected, is connected to the USB 3.0 Host Controller.
1-9. There is a possibility that BSOD occurs when more than one device with the same VID/PID and serial number is connected at the same time on enabling the driver verifier.
1-10. There is a possibility of BSOD when Hot plug operation is done with the xHCI Backwards Compatibility Tree.
[2. Solved interoperability issue caused by function driver]
2-1. A specific web camera does not work by using the specific function driver. This function driver sets the bad Frame Number when the function driver starts the ISO transfer request.
2-2. There is a possibility that BSOD occurs if a function driver behaves as causing a conflict between a transfer request and cancelling the transfer for the same endpoint. We have never seen these drivers.
[3. Add function]
3-1. Added the registry of SymbolicName when a device is connected.
