I have the excellent Taichi Z390 replacing my Z77 Fatal1ty Pro. There is an issue with a device causing intermittent, frequent USB failures. My problem is I have practically every port populated and don't know how to locate this problem port on the board.
Treeview gives me *this* information on the troublesome port:
+++++++++++++++++ Device Information ++++++++++++++++++
Device Description : Unknown USB Device (Device Descriptor Request Failed)
Device Path : \\?\usb#vid_0000&pid_0002#5&17411534&0&1#{a5dcbf10-6530-11d2-901f-00c04fb951ed}
Device ID : USB\VID_0000&PID_0002\5&17411534&0&1
Hardware IDs : USB\DEVICE_DESCRIPTOR_FAILURE
Driver KeyName : {36fc9e60-c465-11cf-8056-444553540000}\0024 (GUID_DEVCLASS_USB)
Driver Inf : C:\WINDOWS\inf\usb.inf
Legacy BusType : PNPBus
Class : USB
Class GUID : {36fc9e60-c465-11cf-8056-444553540000} (GUID_DEVCLASS_USB)
Interface GUID : {a5dcbf10-6530-11d2-901f-00c04fb951ed} (GUID_DEVINTERFACE_USB_DEVICE)
Enumerator : USB
Location Info : Port_#0001.Hub_#0002
Manufacturer Info : (Standard USB Host Controller)
Capabilities : 0x64 (Removable, SilentInstall, RawDeviceOK)
Status : 0x01806400 (DN_HAS_PROBLEM, DN_DISABLEABLE, DN_REMOVABLE, DN_NT_ENUMERATOR, DN_NT_DRIVER)
Problem Code : 43 (CM_PROB_FAILED_POST_START)
Address : 1
Power State : D3 (supported: D0, D3, wake from D0)
I can't correlate this information with the board's schematics as published by Asrock. I assume the important location info is "Port_#0001.Hub_#0002" which I can't translate into a physical location on the board. Can anyone please advise the physical location of this port? I can then unplug the device which is causing the problem and use a different device because I know it is not the board which is malfunctioning.
Thanks in advance...
