And the command lsusb could display the device.And this is some detailed information I think

And my machine information is
Linux ubuntu 3.2.0-49-generic #75-Ubuntu SMP Tue Jun 18 17:39:32 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

And the temporary method to solve the problem is to reboot.
An easy way to reproduce this issue is just to suspend your machine and then wake up the machine.

Please help me.I am looking forward to your update....Thanks.
