AM3352 USB网卡与U盘冲突

Other Parts Discussed in Thread: AM3352

wince 7.0,cpu是AM3352,网卡是AX88772C USB百兆网卡。

因为板子只有1个USB口,所以接了一个hub;U盘、网卡都是接到hub上

单插网卡工作正常,单插U盘也工作正常(同时插3个都没问题)

只要插上USB网卡,U盘就没了,重新插拔U盘也没有用,拔下网口,U盘自动恢复正常。(禁用USB网卡现象也类似插拔)

排除了供电不足的可能性。

感觉和USB buffer关系比较大,但是网上看到有文章是针对6410的:bbs.csdn.net/.../391952039

最好是通过修改注册表的方法解决
