在使用TMS320DM36x TI官方开发板，uboot，内核，文件系统等都使用官方SD卡中的原配二进制程序，上电接上USB鼠标后报错，一直打印：

hub 1-0:1.0: unable to enumerate USB device on port 1

TI官方开发板不会这么不靠谱吧

怎么解决？

    用官方原配的鼠标会出现上述错误

    换成自己的鼠标不报错误：

    usb 1-1: new low speed USB device using musb_hdrc and address 3
    usb 1-1: configuration #1 chosen from 1 choice
    input: USB Optical Mouse as /devices/platform/musb_hdrc/usb1/1-1/1-1:1.0/input/input2
    generic-usb 0003:0461:4D81.0002: input: USB HID v1.11 Mouse [USB Optical Mouse] on usb-musb_hdrc-1/input0

    但是，板子上LCD触摸屏不响应鼠标：不能移动光标。

    请先确认通过有源usb hub连接是否有该问题

    手头没有有源usb hub，有一个无源usb hub，接上不顶用。

    最后换了自己的光电鼠标，能点击YUV输出到电视上的确定按钮，可以测试摄像头采集和编码。

    鼠标还是不能控制LCD上的界面。
