Sometimes it can take up to 3 reboots before the problem goes away.

    There has to be a daemon or something that can be restarted to fix this, right?
    I have had this problem intermittently as well for some time. And its kind of a hard bug to search for due to the generic terms.
    I usually reboot, but for me Ubuntu is a slow booter and it sucks when I have to do it twice in a row.

    I haven't tried it for this issue, but something along these lines just might kick it in the nuts enough to get it going.

    Basically unbind and rebind USB:
    tward $ lspci | grep USB
    00:1a.0 USB controller: ...
    00:1d.0 USB controller: ...

    Then do the following:

    tward $ echo -n "00:1a.0" | \
    sudo tee /sys/bus/pci/drivers/ehci_hcd/unbind
    tward $ echo -n "00:1a.0" | \
    sudo tee /sys/bus/pci/drivers/ehci_hcd/bind

    I have the exact same problem, Dell E6410 laggy mouse from time to time.. currenly running Linux Mint 14, but its the same in Ubuntu 12.10

    TheodoreWard solution worked fine, created a script for it:

    Code:
    #!/bin/sh
    # Buttkicker script
    
    sudo echo -n "0000:00:1a.0" | tee /sys/bus/pci/drivers/ehci_hcd/unbind
    sudo echo -n "0000:00:1d.0" | tee /sys/bus/pci/drivers/ehci_hcd/unbind
    sudo echo -n "0000:00:1a.0" | tee /sys/bus/pci/drivers/ehci_hcd/bind
    sudo echo -n "0000:00:1d.0" | tee /sys/bus/pci/drivers/ehci_hcd/bind
    Thanks

    Re: Slow USB mouse after upgrade to Natty.

    Hi same issue here. I have Dell Lattitude E6510 running Ubuntu 12.10

    uname -a
    Linux unitra 3.5.0-44-generic #67-Ubuntu SMP Tue Nov 12 19:36:14 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

    I also noticed that If I connect the mouse to the docking station everything works fine, and no lag issue ever happens. Also I have custom USB device (STM32F4 USB OTG, ST's USB stack) which performs interrupt transfers extensively (just like mouse, but single transfer is 64B wide), and when connected to notebook's USB ports it sometimes hangs, but when connected to the docking station it works seamlessly (but of course my device may be buggy as well). Can it be that latitudes have buggy USB hardware, and kernel works fine?
