In one of my Vistas 6 files were missing in the first directory and one
driver in second.
Although I fixed that it did not resolve the story completely. I had this
problem for many years in XP and then in Vista.
What I ended up doing after a person from another forum suggested me to do
was to purchase a Belkin Internal 5-Port USB PCI card. He purchased
Belkin's. I did not quite trust the maker but went for his pointer. It
resolved the eissue completely. I removed a firewire PCI card in the back
that I never used and plugged in Belkin. It isntalled itself and I've never
had any problems since.
This card and similar cards by other makers allow for the 5-th USB port to
be engaged. It is not exposed to the elements. It faces the internals of the
computer. However, if you have a floppy you do not need you can buy another
External USB card (not PCI) and mount it up front ripping off the floppy
drive. Thus you will have 8 fully functional USB ports and they will all
work.
I did it on 2 machines so far. I do not need to use the 5th, internal port.
I now have plenty.
