    PCIe usb3 card random disconnection

    Hello,

    I recently bought and installed a PCIe usb3 card (fresco logic FL1100EX).
    It works great under windows, but under my kubuntu 15.10, it works for a time and then disconnects my connected usb devices (printer, phone, disk, ...). Then I can't reconnect anything without a reboot.

    I there a way for me to understand and perhaps fix this strange behaviour?

    Some more information

    lspci -v give me this :

    02:00.0 USB controller: Fresco Logic FL1100 USB 3.0 Host Controller (rev 01) (prog-if 30 [XHCI])
    Subsystem: Fresco Logic FL1100 USB 3.0 Host Controller

    Kernel driver in use: xhci_hcd



    cat /var/log/syslog | grep xhci give me this :

    xhci_hcd 0000:02:00.0: HC died; cleaning up


    We can see in the end the disconnection
