楼主
经过修改 host1 为 usb 接口 ，原装的 usb host 1 是接了硬盘接口 JM20329 经过测试时 是可以识别移动硬盘，
后来修改了 usb host 1 电路做 普通的 usb 接口 来使用发现 usb 识别不了U盘和其他普通的usb设备 ， 请问 是不是要修改 usb host1 的驱动 吗？
而我另外的一个 usb host2 以前原装的板子是接 hub 的现在 我们修改电路去掉了 hub 直接接出来 做usb 口 是可以识别设备 。
现在是问题是usb host1 直接接出来是没有用的。
以图片是我的电路图 是usb host1 的电路图 （应该是没有问题）， 大家看看是我驱动要修改 还是 电路图有问题，怎么解决这个问题
dts 我也是没有修改过的和 原本sdk 的dts 一致，以下是我的dts 相关usb 是否要修改 dst 请 帮忙指导一下。谢谢。
