Re: [issue979] Slow, failure-prone USB mass storage (SB600? msdosfs? CAM?)

    Well, if Linux is also blowing up on it then it is either going to be
    the USB chipset on the motherboard, or the device plugged into or
    otherwise connected to the USB.

    If other USB mass-storage devices work (for example, if you plug in
    a usb storage key and that works ok), then it is likely the device
    plugged into the usb slot and not the usb chipset that is to blame.

    If no mass storage devices work then it is likely an issue with the
    usb chipset or driver.
