    Hi Amanda,

    Kernel 3.4 is a bit old, therefore the xHCI driver stack will not have the latest changes/fixes so the behavior of the TUSB7340EVM may be a little bit unstable (as you are experiencing). My first suggestion is to update your system with the latest stable kernel version available at kernel.org this way you'll get the latest xHCI driver stack.

    Best Regards,

    Alexis Cortes.
