我这边（rockchip reload）貌似也遇到类似你的问题。只不过我这边使用的本地编译的版本。
操作步骤：使用新下载sync到最新代码，然后修改支持lcd，tp，sensor部分代码；编译烧写版本， Android 5.1；
sudo rkflashkit flash @boot boot.img @kernel kernel.img @recovery recovery.img @system system.img reboot
现象：连接PC，弹出“unfortunately, device test has stopped”，发现usb的功能mtp，adb都无法使用；
log分析：

由此，usb没切换到device mode导致的问题。
问题：请问下rockchip reload的板子usb otg的driver文件主要是哪几个？ |
