USB no longer 2.0 after XP reinstall

[mstenzel]

I had to reinstall XP recently and ever since my 3+3 USB 2.0 PCI card (3
ports attached
to card in back of PC and 3 ports in the front accessible hub)is only
running at
USB 1.1 speeds. I updated to SP2 right away.

XP gives me the warning that "This USB device can perform faster..." The
current
drivers for this card appears to be "usbd.sys" and "usbhub.sys" - both
located in
the system32\drivers directory (I got this info from Device Manager under
the USB
controllers section). The actual controller names are "ALi PCI to USB Open
Host
Controller" (I got this info from the "HI-SPEED Device Attached To
non-HI-SPEED Hub"
dialog box that popped up with my warning.

Interestingly, the driver disk that came with my card/hub installs the
drivers "ousb2hub.sys"
and "ousbehci.sys" into a "C:\WINDOWS\Drivers\ousb2" directory." I'm
confused because
I don't know which are the right drivers. Everything I've read online seems
to say
that the usbd.sys and usbhub.sys drivers are the standard XP USB 2.0
drivers, yet
the install disk put in the others. I've tried having all of them in the
system32\drivers
folder and I've tried leaving the "ousb2hub.sys" and "ousbehci.sys" ones in
their
original folder, but neither way works.

Before my XP reinstall, I had 2.0 speed, so I don't think there's anything
wrong
with the card or hub. I'm guessing there must be a driver conflict
somewhere or
some other missing file. Any suggestions are hugely appreciated.

Thanks.

Actually XP SP1 installs the 2.0 for USB,open system properties,device mgr,
scroll down to USB controller,R.click,then select,update drivers,let xp
update
auto,there's no reason for searching it'll find them for you...

Andrew,

Thanks for taking the time to reply. I followed your instructions to the
letter,
but nothing has changed. I actually have done different versions of that
process
several times before I posted here -- I've uninstalled/reinstalled card,
uninstalled
drivers and scanned for hardware changes, and so on. I can't figure out
what's going
on.

Could it be a driver conflict? I migrated some settings using XP's Settings
Transfer
process off of its install disk. Could I have brought over a driver I no
longer
need and it's conflicting with the USB card? What would happen if I deleted
my driver
files and let Windows re install all that it needs?

Device Manager says that the drivers are "usbd.sys" and "usbhub.sys" so I
don't know what else can be changed if those are the right drivers.

Very frustrating.
