I have Asus-P4SDX MB. When suddenly my USB webcam device not enumerated, I check the Bios Setting and I see that feature "boot virus detection" dissappear. I scanned computer with Norton Anti Virus, and no virus found.
I check device manager and I see no problem with sis 7001 USB Device. I visited usbman.com and tried whatever they told to make my USB Device can be enumerated, but nothing changed. I even reinstalled my windows XP but still no change. I updated my Bios with the latest(ver.1003) and clear the RTC RAM in CMOS but still no change.
I open regedit and found that in HKLM\System\Current Control Set\Enum\PCI\dev7001\control I see in FilteredConfigVector, required device type is Memory not Port. I change it with modify binary data and my USB device can working. But when I reboot the old value back and I must change again to able to use my USB Device. I changed permissions in this Control to read only, but when I reboot, error blue screen appear and automatically reboot. I thing the problem maybe in BIOS, so please help me to repair this.

I try my webcam to other computer and it can work. I think the problem not in driver but in enumerating port USB. Thank you. Please help me.

What is the make of your camera, its installed software, and do you have any other USB devices you can try on the computer?

I have PC-Cam Creative 880 Camera. Usually the storage device on it enumerating automatically, even if I have not installed driver. I have other PC-device's, usually if I don't install device driver, in lower right on display will appear command to install driver. But now, no happen, even not any error notice appear.

Not familiar with WinXP, so I can't help you there.

Also not sure of your registry key information...I'm assuming you got that info from USBMan.com...

I'm assuming this setup worked OK in the past...

All I can suggest is to completely uninstall the camera and it's software, and reload it per Creative's instruction. The camera should enumerate properly when the install asks you to mount the device. If not, I'd say to check Creative's website for further troubleshooting steps.

Good Luck!!

I have done what you told me and visited Creative web site, not helped.
I try to use other USB devices, but none is worked. Thank you anyway. I just wonder how to maintain my registry value, so it can not change to old bad value.

Try exporting the key to a .REG file and run regedit at startup to import it.

Just curious where you got this registry key info from...can you post a link?
...HKLM\System\Current Control Set\Enum\PCI\dev7001\control I see in FilteredConfigVector, required device type is Memory not Port...
I went to USBMan.com and saw your post...Bill can be a bit of a p***k sometimes...I didn't like how he dealt with me when I challenged him on an issue I was having in the past...
