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.
I have a Foxconn 661FX7MI MB which has an SiS964 southbridge which
apparently supports 8 USB2.0 ports running a Phoenix- AwardBIOS.
Currently Device Manager is showing:
3 x SiS7001 PCI to USB Open Host Controllers
1 x Standard Enhanced PCI to USB Host Controller
4 x USB Root Hubs
I forced the Enhanced Controller but obviously it is not seeing my
Mass Storage Device(Gizmo)
After a few more hours I discovered that if I turn off USB2.0 support
in the BIOS then XP recognises my Gizmo etc. but tells me that it
would run faster if I had a high speed port! If I turn it on then XP
locks up conversly in Vista with it on Vista ignores the Gizmo and it
is identified as an Unknown USB Device.
Apparently SiS don't provide a USB2 driver Microsoft does but I can't
find it!
Should I try to install all the Enhanced USB drivers regadless of
brand untill hopefully I find one that works or what?- Hide quoted text -
