DM8168 USB鼠标问题

DM8168 USB接鼠标时，一些鼠标会经常断开连接。有的鼠标不会。接键盘和U盘之类都很稳定，没有问题。SDK使用官方最新的。这个会是什么原因造成？

    你用的是什么SDK？PSP的版本是多少？你用的是TI的EVM么？

    使用RDK 3.0，自己的板子，在EVM （udworks 的DVR开发套件）上试也是一样的情况。以前有使用过EZSDK 5.02版本，也是这样的情况。经常断开的鼠标，有时候都识别不出ID。

    你好！
       请按照下面的步骤把log贴一下：
    1.       Enable debug level:  echo D8 > /proc/driver/musb_hdrc.1 (or musb_hdrc.0 based on which port you tested).
    2.       Clear the logs by command “dmesg -c”
    3.       Check the interrupts counts “cat /proc/interrupts”
    4.       Reproduce the issue
    5.       Check the interrupts and dump the logs (dmesg)
    6.       cat /proc/driver/musb_hdrc.1 (or musb_hdrc.0)

    经过反复验证，我们使用的鼠标 使用原相 PAN3512DK 这颗芯片的都会在1分钟左右断开连接，然后重新识别。而其他的鼠标不会。这些都是在没有加载上层设备驱动的情况下。加载上层设备驱动后就不会断开连接。
