got this data cable for LG2030, got the driver CD (meant for XP) along it, and Vista did the rest of locating the drivers from the CD to install the 2 drivers, and I had it work perfectly. A week later, I was doing Windows Update, and it showed an optional update for the driver of the USB converter for the data cable. I started downloading it, and just before it was going to get over, the internet connection got disrupted, and the download failed. Then on, whenever insert the data cable into the port, Vista shows a blue screen (not BSOD) showing stop error to prevent damage to computer and recommended me to reinstall the drivers. Once I uninstalled the drivers, and inserted the data cable, it just didn't say found new hardware nor asked me for the drivers. It just didn't work. Sorry for the long explanation. Please try to help me out!
See if you can roll back the driver in the device manager. If not reinstall the old driver. The next time you go Windows Update just hide that update. Also go to the manufacturer's web site and see if they have a recent update for the device. The reason it didn't show the error after you unplugged the device is because the computer no longer recognized it as being a problem device (it wasn't plugged in).
Remove driver and reinstall with a fresh driver
