    Angry USB Hell

    My desktop pc has four USB ports - Two on the front & two on the back. I know they all work, both from when I had Windows installed & because my external HDD works on the two front ports, and my printer from the two back ports.
    All is well...Until I need to copy files from my external HDD to a flash drive. I connect ANY flash drive (tested 4) to one of the ports in the back, and I can see it in Nautilus, through fdisk -l and everything. But when I try to open it...It either doesn't work at all or starts spewing I/O Read-Write errors and gets reset, and starts all over.
    And all those drives work perfectly on the two front ports, and everywhere else...Just not on the back ports?
    Any ideas?

    Hi sorry to hear you are having problems you could try the following command to list your USB devices the system recognizes.

    First you can update the list itself so that you have the most up to date list in your system for it to list your drives correctly

    Command to update USB deivce list
    sudo update-usbids

    Command to list USB devices detected by Ubuntu in your system

    Please post the results of lsusb with several of your drives connected and I will try to see what the problem is, If I can't it will give someone else wiser than I a better understanding of your problem.

    Also please try to give any errors you are seeing so someone can diagnose that as well.

    This is what i get with my external HDD on the two fronts ports,
    and my Creative MuVo & and a 2gb flash drive on the back ports.

    As for the errors... strangely - this time, everything works perfectly...
