[ubuntu] USB 3.0 is too slow

view full story

http://ubuntuforums.org – Hi, I am asking for help to find out how to make USB3.0 working faster than USB2.0. At the moment it is recognised as USB3.0, but only gives me USB2.0 performance and I wonder whether it is possible to make faster! Hardware: Dell laptop Latitude E6520, it does not have the built-in USB3.0 port, so I have to buy the PCI Express Card (EC). The card is Startech ECUSB3S2 USB 3.0 Expresscard (http://intrl.startech.com/Cards-Adap...er~ECUSB3S254F) I am under ubuntu 11.10: aa@aa-i7:~$ uname -a Linux aa-i7 3.0.0-13-generic #22-Ubuntu SMP Wed Nov 2 13:27:26 UTC 2011 x86_64 x86_64 x86_6 (Hardware)
