Dear all,

      I met one strange problem:

     some devices would report below errors all the time:

[ 44.245689] hub 2-0:1.0: connect-debounce failed, port 1 disabled

[ 46.755714] hub 2-0:1.0: connect-debounce failed, port 1 disabled

[ 49.175681] hub 2-0:1.0: connect-debounce failed, port 1 disabled

[ 51.575672] hub 2-0:1.0: connect-debounce failed, port 1 disabled

[ 53.975690] hub 2-0:1.0: connect-debounce failed, port 1 disabled

[ 56.375884] hub 2-0:1.0: connect-debounce failed, port 1 disabled

 

    When these devices reported this error,sometimes the devices cannot wakeup from

suspend mode.

 

Do anyone met this problem ?How to solve it ?

 

Thanks very much for your support!

1.The devices software is android 4.0.4,and the kernel version is:Linux version 3.0.35-05375-g53040e6-dirty;
