EKF is a manufacturer if industrial I/O boards, here the SBX-DUB, equipped with 4 x TUSB7340.
A customer reports a serious problem, showed up in a message 'Windows has stopped this device because it has reported problems (Code 43)' , TI USB 3.0 xHCI Host Controller Properties, Windows 8.1 Embedded Industry Pro.
Microsoft support comments: „AFAIK TI has only released one USB 3.0 controller which was fully hardware based, and used a pretty early version of Synopsys xHCI IP. Code 43 means that usbxhci.sys driver is claiming an unrecoverable xHCI controller hardware problem.”
The problem occurs only when large data packages are transferred. The CPU load afterwards is nearly 100%. In order to recover from this fault the complete system must be restarted.
A larger Microsoft Message Analyzer trace file would be available for TI debug.
