Hello!

I recently bought a new Canon Scanner which is USB. I also upgraded my computer's motherboard which has two USB slots built in on it, along with installing Windows 98 for the USB support.

Windows runs fine, except it doesn't recognize my USB port (controller) in device manager. One odd thing that is happeing is that an "unknown device" is listed. I belive this is the culprit. I have a friend who has an almost identical computer as mine and Windows recognizes the USB port and lists no "unknown device".

So...I guess my question is how I can get Windows to recognize my USB port? I've tried going into Add/Remove hardware and adding a USB controller, but I'm not sure which driver for the USB port to use. Any help would be appreciated...thanks for reading

We really need to know what kind of board you upgraded to (LX,BX,ALI, Apollo?) and it's Brand name.

My motherboard is a Biostar M5ALA with the ALI chipset.

Thanks for responding...

Check the CD which came with your mother board for any patches or fixes you may need to install. Also, if you are using Win 95 you may need to install USBsupp.exe and USBupd2.exe found here on the Win '95 CD:

I have a biostar m7kma motherboard with athlon 550 processor. When I plug in my Logitech wingman force usb I get Unknown Device under usb in device manager. I have downloaded all drivers and patches,even one from Microsoft that states this problem and said their patch would solve it...it did not. Any help would be appreciated.. Otis23

I've a FIC VA503+ with the current bios. Win 98 doesn't recognize a Logitech Wheelmouse on USB. It set up the PCI to USB bridge just fine but continually detects the mouse as an unknown USB device and not a mouse. The USB is on in the CMOSbut the only other setting for USB is keyboard with the options of DOS/SETUP. FIC say its windows. Windows says it Logitech Logitech says its the chipset.
What gives ??

I have als9o got the same problem of a FIC VA503+ motherboard with a USB riser. When i plug in a Kodak DC280 i get unknown device.
I installed usb view from the win 98 res kit and it said
device failed unknown enumerator

Does any one know any answers???

I have the same problem I have windows 98 SE and I bought the usb card to update for a video camera and my system does not recognize the correct driver I need the driver VIA VT83C572/VT 82C586 where can I down load this driver?

I've bought CanoScan FB 620U, then I've bought motherboard Elite P6BAT-A+ on Elite chipset ET82C693A/596B and Celeron 466.
THe problem I have is I can't find my scanner under Win 98. The first time I've installed drivers for scanner, the system saw the scanner, but now it can't see it. What I have to do??? Pls help me!!!
May it's because I have Riva TNT/2 ??? (I mean conflicts between AGP & USB ports?

I tried to install a Canon FB630U Scanner on a Compaq Presario Pentium III 500MHz Windows 98 SE PC. First I could not install it. Then I changed to the other USB port. Then the system could identify the scanner. After one month of not using the scanner, Win 98 SE only finds an Unknown Device there. First with a red cross (disabled, Code 22), then after restart with yellow exclamation mark (not all drivers installed bla bla,Code 10). I tried all drivers from Canon, Windows 98 SE still insisted that usb.inf would be the best driver inf file and would not accept the FB63u.inf file that comes with the scanner (the location specified does not contain information about your hardware). I changed the cable, I tried to install the scanner on a different machine. Today I returned the scanner to Canon, because I believe, that my first assumption of mismatching USB signal voltage (the scanner is powered via the USB port) is wrong and that I just had tough luck. From all I have read during one night of trying to fix this, I got the impression, that there is a lot of uncertainty regarding USB out there. I also found registry entries from the USB Enumerator from the first installation. I found entries that the inf file should be in c:\windows\inf and in another registry entry it should be in c:\windows\inf\other. My impression after a night with two hours of sleep is, that USB is (also) not free of glitches (yet).

I had the same problem with an older motherboard, DTK. Turns out it was the USB pins were damaged. The uniqueness of it all is that I had two boards exactly identicle.

The other boards' USB worked. The problem I have now is that I can't use both ports at the same time. I can plug a device to one or the other, not both. Never managed to solve this problem yet.

Same issue PC Chips Ami intergrated mobo with PCI USB riser. The USB configuration appears to be correct, when I install my Logitech camera it detected a camera and uinstalled the driver and the camera worked. Next time I restarted the computer there was no camera in device manager, just an unknown device under USB in device manager. No matter what I try now I can't get the camera to work.

I have the same problem, bought a new HP computer and tried to hook up my usb HP Scanjet with the windows ME. I am told that the usb port needs an upgrade to a usb.inf but no one seems to know where to get it from. Intel told me to go through HP and they give me the run around. HELP!
