** Description changed: The following error happens while plugging in defferent type of USB modem dongles. My computer originally had Ubuntu 12.04-3 LTS installed which was upgraded to 13.10 and then finally to 14.04 LTS. This error was not evident on the earlier versions, only with 14.04 LTS. On first plugging the USB modem dongle in, there is no problem and it works correctly. If however, the USB modem dongle is unplugged, and then plugged in again a short time later, the error is seen and no further USB modem dection/removal will take place until the computer is rebooted. On shutting down, the shutdown process locks up and I have to hold the power button in for a couple of seconds to actually power off the computer. lsb_release -rd Description: Ubuntu 14.04 LTS Release: 14.04 The results from the kernel log are shown here.
