For the past year or so I have been connecting a Flash Card Reader to my pc. It always showed up as a drive and could work with it normally. One month ago for no apparent reason my Dell computer will not recognize the card reader....the green icon will come up when I connect the reader but the card contents does not show up nor does a drive with drive letter show up. If I plug the card reader to another computer it works well.
Funny thing is that I have a portable USB drive and that one works fine on the Dell that does not recognize the compact flash reader.
I have done all of the following.
New card reader
New compact Flash card.
Uninstalled and reinsalled drivers
Tried different USB ports
Reinstalled drivers for USB ports
Reinstalled windows but not a complete install.
Ran every conceivable diagnostic utility but nothing came back as a red flag
I have not installed nor removed any programs.
Please any ideas would be helpful
