TMS320DM36x TI官方开发板 LCD不响应USB鼠标



刚开始用官方原配鼠标,会报错,不能枚举USB设备

用自己的鼠标可以正常识别USB鼠标设备

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,LCD不响应USB鼠标输入,不能移动光标,怎么解决。
