This USB device can perform faster if you connect it to a Hi-Speed

After installing Windows XP SP3 RC1 my system wouldn't boot. In safe mode I
ran the uninstaller for the service pack but it aborted. I had to restore my
hard drive from a backup.

After that, my external USB drive starts working properly, but after some
time I see the message "This USB device can perform faster if you connect it
to a Hi-Speed USB 2.0 port".

In Device Manager the drive is flagged with a message saying the device
driver can't be loaded because another copy is in memory. The drive letter
disappears.
When I look at the device list by connection I see that the drive is moved
to a different USB port - non-USB 2.0, but originally it was connected to an
enhanced USB port.

It looks as if the OS has deliberately switched the drive to a different
port running at a lower speed and then told me it could run faster. If I
unpug the drive and plug it in again or restart it works fine for a while
until this happens again.

None of this makes sense and this had been working fine for a long time
before this abortive update to SP3.

I would appreciate any advice on how to fix this.

My system is an HP Pavilion with AMD dual core X2 4200+, SP2, 2GB Ram.
The USB drive is an HP Media drive that loads into the front bay slot. Priot
to this I had no trouble with the drive. I use it for nighty backups. When
this problem occurs an error is logged in the system events listed as 'ftdisk
- The system failed to flush data to the transaction log. Corruption may
occur.' I ran chkdsk after that and so far there have been no errors.

This is what comes of installing a *beta* service pack on a production
machine and why you shouldn't do it. That said, try reinstalling your
motherboard drivers (chipset). Get them from HP's website for your
specific model machine. While you are at HP's site, if there are other
drivers that might pertain to USB, download/install them too.

If reinstalling the drivers doesn't help, then back up your data and
restore your computer to factory condition. If you want to do beta
testing and don't have a second testbed computer, buy an external hard
drive and imaging software such as Acronis True Image and get into the
habit of imaging your system often.

Thank you for your reply. I downloaded the chipset drivers but that made no
difference.

Naturally I am aware of the dangers of using beta software - the standard
Microsoft
update releases are not without hazard either. However, RC1 is not the same
as beta and many users on some audio forums I frequent have raved about the
performance gains and none complained of problems, so it seemed like a low
risk.

Having regular nightly backups (on external drives) , I wasn't too worried,
but obviously there are even hazards in backup software.

I have tried imaging software in the past - Driveimage (no longer available)
and
Ghost. Ghost comes with too much Symantec baggage for my taste so I no
longer use it.

I am currently using Retrospect and I will give Acronis a tryout.

By the way the drivers I have are -

The drivers on the Enhanced USB Controllers are:

usbehci.sys 5.1.2600.2891
usbhub.sys 5.1.2600.2180
usbport.sys 5.1.2600.2891
hccoin.dll 5.1.2600.2180
usbui.dll 5.1.2600.2180

The drivers for the hubs are:

usbd.sys 5.1.2600.0
usbhub.sys 5.1.2600.2180

The drivers for the HP Media Drive is
USBStor.sys 5.1.2600.2180

and for the ST340083 2A USB drive inside:

disk.sys 5.1.2600.2180
partMgr.sys 5.1.2600.0
 
Well, I think I fixed it. I made 2 changes and one or both fixed the problem:

1) changed performance mode from Background and System cache to Programs to
use smaller pages

2) changed BIOS setting to load Plug and Play BIOS from NO to YES.

When I rebooted an Unknown USB Device was discovered in a Root Hub.

After that everything seems to be OK.
 
It has been a while since I fixed that problem in the RC1 SP3 release.

The problem came up for many other users in the final release.

It turned out to be due to HP installing Intel drivers on an AMD CPU!!
