lx2160 usb over-current condition

[2916341676]

我在尝试将读卡器插入2160板子时发现没有识别到我的设备，使用dmesg | grep "usb"，发现有以下打印：

usbcore : registered new interface driver usb-storage

usb usb1-port : over-current condition

usb usb2-port : over-current condition

usb usb3-port : over-current condition

usb usb4-port : over-current condition

作为一个新手，我该如何解决这个问题？请帮忙给出解决步骤

If the board work as OTG, please compare the USB part schematics with the LX2160ARDB schematics, page 49,USB2.

问题已经明确了，原因是硬件电路不合理导致的过电流问题，感谢您的帮助
