Hi all,
It appears that I'm one in a growing number of people with this
problem, so I figured I may as well jump in! I recently upgraded to
Vista Ultimate and backed-up all my XP files (music, photos, etc.) to
a brand-new Maxtor OneTouch III external USB drive. After installing
Vista, the drive was detected as a mass storage device and worked like
a charm (this was about a week ago); I've used it up until yesterday
with no problem. I also have an iPod Shuffle and a USB memory stick
that both detect as mass storage devices, and they worked fine as
well.
Yesterday, I went to burn a CD from some music files stored on the ext
HD, only to find... none of those three devices listed in Explorer!
Naturally, I tried unplugging and re-plugging the ext HD. After a few
seconds, Vista says 'installing drivers for your device' and then 'usb
device unrecognized' -- no dice. I tried unplugging, powering-down,
and re-plugging the drive -- no dice. I even tried unplugging,
powering-down the drive, rebooting the computer, then re-plugging the
drive -- still no dice. It always tries to install some driver (no
specifics given) and then fails to recognize the device.
The closest I've come (and this is interesting) is by uninstalling the
USB Controller device listed in Device Manager. Immediately after
uninstalling, Vista detects all 3 of my devices and pops-up the
explorer browser windows for each! I was stoked, until... 'installing
new drivers', 'unrecognized device', *poof* they all disappear again
from Device Manager and Explorer. So close.
What have I done between the time those devices worked and yesterday?
1. Extracted the GART driver from the Nvidia nForce 5.11 XP driver
package and installed it (my FPS in games were absolutely horrid until
I did this).
2. Disabled indexing (for performance)
3. Installed my 3rd gig of RAM (now running at 3GB RAM)
4. Set my CPU to high performance in Power Options
Here's my system specs:
AMD 2800+, 3GB RAM, Asus K8N mobo (nForce3 250 chipset), GeForce
7800GS OC AGP
I've already installed all the Vista updates I can find, and tried all
the power-off/on combos mentioned by everyone else. No, the ext HD
doesn't appear in disk management nor explorer or device manager. I
know my mobo is USB 2.0 compliant, and that all 3 devices worked only
a few days ago without a hitch (eliminates faulty devices, power
issues, etc.). I've found the following MS KB articles and will
investigate more when I get home: http://support.microsoft.com/kb/925528,

Any additional help/troubleshooting would be greatly appreciated!
