Shows device information events at the beginning of the trace and captures the starting state of the USB tree. The events are not included in the Default keyword. Shows driver-internal state machine transitions. The events are similar to USB 2.0 ETW events but do not include any USB transfer events. Shows events that are useful for general troubleshooting. #HOW TO UPGRADE USB HOST CONTROLLER WINDOWS 7 DRIVER#Here are keywords for filtering USB 3.0 driver stack events: ETW keyword You can filter events based on keywords depending on your requirements. Note that this method of filtering is for use at capture time, not during analysis. Events that match any of your keywords are saved. #HOW TO UPGRADE USB HOST CONTROLLER WINDOWS 7 DRIVERS#You can use ETW keywords to filter the events that USB drivers write to a trace log and customize how much information you want to view about events captured from the USB 3.0 driver stack. Those words are ETW keywords that indicate the types of events you want to view. Notice ETW keywords such as Default and PartialDataBusTrace in the Logman capture commands. RemarksĬapture filters for USB 3.0 driver stack events You can do so by modifying the command sequence shown in step 2 to remove the "logman update" lines corresponding to the driver stack you want to remove from the trace session. If you want to reduce the event traces to just one USB driver stack, remove the other driver stack from your next trace session. The file contains event traces from the USB 3.0 and USB 2.0 driver stacks. Move the file to another location or rename it in order to avoid overwriting it when you capture the next session. The trace file is stored at %SystemRoot%\Tracing\usbtrace.etl (C:\Windows\Tracing\usbtrace.etl). The preceding capture session generates an etl file, named usbtrace.etl. Move /Y %SystemRoot%\Tracing\usbtrace_000001.etl %SystemRoot%\Tracing\usbtrace.etl You can stop USB hub and port event collection by running the following command: Enter these commands to end the capture session: Stop the session after you have completed the scenario. For example, to capture events for device enumeration, you can plug in a USB flash drive that shows up as an "Unknown device" in Device Manager. Perform the operations that you'll want to capture. #HOW TO UPGRADE USB HOST CONTROLLER WINDOWS 7 UPDATE#Logman update trace -n usbtrace -p Microsoft-Windows-Kernel-IoTrace 0 2Īfter each of these commands completes, Logman displays The command completed successfully. Logman update trace -n usbtrace -p Microsoft-Windows-USB-USBHUB Logman update trace -n usbtrace -p Microsoft-Windows-USB-USBPORT Logman update trace -n usbtrace -p Microsoft-Windows-USB-USBHUB3 (Default,PartialDataBusTrace) Logman update trace -n usbtrace -p Microsoft-Windows-USB-UCX (Default,PartialDataBusTrace) Logman update trace -n usbtrace -p Microsoft-Windows-USB-USBXHCI (Default,PartialDataBusTrace) Logman create trace -n usbtrace -o %SystemRoot%\Tracing\usbtrace.etl -nb 128 640 -bs 128 In the command-prompt window, enter these commands to start a capture session: To do so, select Start, type cmd in the search box, Select and hold (or right-click) cmd.exe, and then select Run as administrator. Open a command-prompt window that has administrative privileges. In that case, you will view new USB 3.0 driver stack events for a USB 2.0 device. When you connect a USB 2.0 device to a USB 3.0 host controller, you get event traces from the USB 3.0 driver stack. You can capture events from the USB 2.0 or USB 3.0 driver stack independently. The way you capture event traces from USB 2.0 and USB 3.0 driver stacks is similar. #HOW TO UPGRADE USB HOST CONTROLLER WINDOWS 7 WINDOWS 8#Event traces from the USB 2.0 driver stack can be captured on a Windows 8 computer. For more information, see Remarks.Įvent traces from the USB 3.0 driver stack are similar to the USB 2.0 driver stack traces, which were introduced in Windows 7.
