[Bug 1345895] [NEW] [Dell Inspiron 3541] USB3 stick speed drop to 480M after first use

 

Public bug reported:

CID: 201403-14859 Dell Inspiron 3541

The USB3 speed is 5000M when the first time you insert it after boot:

ubuntu@201403-14859:~$ lsusb -t

    |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/4p, 480M

But if you remove it and plug it to the same USB3 port again, it will drop to 480M:
