您好，

我有采用NXP处理器和带PCIe接口的TUSB7320的定制主板。 PCI检测到USB控制器。同时检测到USB 3.0 集线器。

但当我将任何设备插入USB 3.0 端口时，其枚举失败，并显示错误-71。我正在使用Linux内核3.14 .................52.

以下是PCI配置空间：

以下是错误：

root~# USB 3-2：设备无响应，设备描述符读取/64，错误-71
xhci_hcd 0000:01：00.0 ：安装错误：设置插槽1的上下文命令。
USB 3-2：设备无响应，设备描述符读取/64，错误-71
xhci_hcd 0000:01：00.0 ：安装错误：设置插槽1的上下文命令。
USB 3-2：设备不接受地址8，错误-71
USB 3-2：设备不接受地址9，错误-71

USB控制器端是否需要任何寄存器配置才能正常工作？
