[hnlbxb2004]

同样遇到这个问题。

[Dizner]

@hnlbxb2004 @dwf131 看这个 https://blog.csdn.net/vspiders/article/details/90201818 需要修改libusb100.so的代码，然后重新编译

[hnlbxb2004]

@Dizner 谢谢，最后就是按照你这个修改的。已经解决了。我见已经有人提了PR 了。

[hnlbxb2004]

我主要就是没搞明白为什么9.0 的系统有这个问题，那一段我没太看懂。为什么会空。

[jjjjbababy]

@Dizner 谢谢，最后就是按照你这个修改的。已经解决了。我见已经有人提了PR 了。

有修改好的so吗？

[Dizner]

@hnlbxb2004 抱歉，不太懂c代码，我也只是处理了问题，并没有查看其发生的原因，无法帮到你

[Dizner]

@jjjjbababy 使用原工程，改一下这段代码，然后ndk编译就行了，时间久远，我这边也没有编译好的so文件了，抱歉
