I have a new install of Vista Ultimate. I have an external LaCie hard drive and two USB flash drives. The first time I plugged in the USB flash drive, I got the window in my task try saying it was installing. The result was the installation failed. This has happened to all my USB devices I I know it is not the device itself. I have plugged each device in each available USB port on my computer and all installs failed. Now, when I plug in the device, nothing happens. Vista does not even attempt to install the device. I looked in device manager, and there is no errors. I looked in Disk Management, and the devices are not listed. What to do what to do?
