Usb 2

Hi,
After installing XP Pro onto my PC a few years old, no USB2 only 1.1. I had a USB2 PCI card installed.
My problem is the scanner that I use Canon 8000F USB2 will not work with Via USB2 drivers only NEC drivers. My USB 2 PCI card has both on the driver CD and when installed somehow the Via drivers installed themselves too.
If I plug my scanner into the USB 2 connectors I get one scan and then the scanner dumps its Twain drivers and I end up installing the scanner drivers again. All works well on USB 1.1 just too slow.
How can I uninstall the USB drivers to try and install the NEC drivers only.
Or should I just buy a new USB 2 card that only has NEC drivers and install it.
I know it can be installed so it works flawlessly it had been done before, trouble is the techie can not remember how.
USB Universal Serial Bus controllers
Generic USB Hub
NEC PCI to USB Enhanced Host Controller (B1)
NEC PCI to USB Open Host Controller
NEC PCI to USB Open Host Controller
USB Root Hub
USB Root Hub
USB Root Hub
USB Root Hub
USB Root Hub
VIA Rev 5 or later USB Universal Host Controller
VIA Rev 5 or later USB Universal Host Controller
This is the USB Stack in Device Manager.
When I connect USB 2 devices Windows always will advice me that this device can operate faster by connecting it to the USB 2 connectors from the PCI card. But when connecting there is problems.
My original USB 1.1 connectors on the front work fine.
Any ideas would be greatly appreciated.

hi Pete,
and thanks, sorry to be draging my feet, but I have been working late.
So what you are saying is that the 2 VIA Rev 5 or later USB Host Controller belong to the Motherboard as my IWill Mobo has the VIA chip and yes the Canon Scanner is happy to run on USB 1.1 but USB 2 is a different matter.
So it is only the NEC drivers that are installed.
My XP Pro has SP2 installed, but I did have the problems once before SP2.
No the PCI card drivers do not show up in Control Panel Add / Remove.
As I mentioned Windows recognices the card as every time I plug in my USB2
card reader or Jump Drive the little message pops up from the Task Bar informing me that this device can perform faster by connecting it to the USB 2 Ports.
Mind you my external hard drive does not like the USB 2 ports eighter no problem in 1.1. There are no yellow markers in the device manager.
The card is in the same PCI slot it was in when it worked fine. I have made many enquiries regarding this but no results. Must be one of those hard to pin point problems. I had been thinking about installing a new USB 2 PCI Card and try again. But how would I uninstall the present drivers to install the ones of the new card, as they do not show up in Add / Remove.
It would be nice to be able to scann with USB 2 speed

hi Pete,
no the message only comes up on the USB 1.1 plugs
I had a look on the drivers and there is a slight difference
youre MS 5.1 2600.2180
mine MS 5.1 2600.0
does this mean That I don't have the latest MS drivers??

I am fairly shure that I have the latest Canon drivers but I will download them as well.
well you found something Pete where to from here

PCI Card but only work on 1.1

Hi Pete,
Sorry I could not hang around any longer last night.
Lets recap as you said.
The Mobo is a Iwill KK266-R it has 2 USB Ports and I think looking at the diagram in the Manual 1 USB 1 header. The Hub 4port on the front USB are USB 1 only it is self powered it used to be connected to one of them it is now connected to the internal port of the USB 2 PCI card that has 4 external plus 1 internal port. The Scanner is plugged into the USB port at the back of the mobo Canon do not recommend to connect to Hubs. All my USB ports work fine on 1.1 but for some time the scanner was connected to the USB 2 PCI card and worked just fine till one of my hard drives went south and had to reinstall Windows and a new HD.
I have not uninstalled the card as yet as you were still contemplating but if you think I should then I will try that first. In regards to connecting the front Hub to the header on the board I have tried that and it made no difference I get one scan on USB 2 and then it dumps the Twain drivers and I have to go through the process of reinstalling the Scanner.

hi,
yes they are Pete.

 

just a update Pete, installed the latest Canon drivers, uninstalled the 3
NEC PCI to USB Open Host Controller as you refered to rebooted the system and Windows reloaded the drivers this time with the same drivers as on your list.
Connected the scanner to the USB 2 ports and tried to make a scan, but as soon as I clicked scan I received the message that the Twain drivers will be shut down. I then used the Canon utility to uninstall the drivers and then reinstalled them and all is well again but only in USB 1.
Back to the Drawing Board I guess.

Have a look at densaw's thread:
http://www.windowsbbs.com/showthread.php?t=45561

It reminded me that there can be problems associated with the printer.

Try uninstalling both the printer and the scanner, then reinstall the scanner before the printer. Look in the User Guide for the scanner, I know it is mentioned in some.

thankx mattman, I don't think that it would apply in this case as both my Canon Printer and Scanner work harmoniosly together in USB1 my Printer is always on USB1 the scanner only causes problems when connected to USB2 and there is no mention in the setup procedure about Printers.

Any comments or advice on these articles I have found.

Microsoft Hub Patch
A patch to resolve the following issue "USB Devices May Not Work After You Unplug a Downstream USB Hub from the Host Controller" is available from Microsoft. 01/23/2003
Download Patch


Removing USB Completely
If USB is sharing an IRQ with another device and you are attempting to free the IRQ, or you need to refresh the USB driver stack, you must remove ALL USB elements completely. Windows will refresh the USB driver stack when you reboot to Windows Standard mode..
Note: Completely removing USB creates problems for users who have both USB keyboard and mouse connected. Change one input device to PS/2 until you have completed the cleanup.
Refreshing the USB Driver Stack
Windows Standard Mode
• Unplug all USB devices except keyboard and/or mouse.
• Uninstall the software for the USB peripheral devices.
• Shutdown and boot to Safe Mode -> Device Manager
Windows Safe Mode -> Control Panel -> System Properties -> Device Manager. In the view Tab Select the Show Hidden Devices Option
The order of removal must be followed exactly
• Delete USB peripheral devices (Scanners, Printers, Cameras etc.)
• Delete HID and/or Composite USB (Human Interface Devices)
• Delete USB Root Hub(s) (Universal Host Controllers)
• Delete USB Host Controller(s) (Universal Host Controllers)
Note: You can Navigate in Safe Mode using the keyboard Tab, Alt, Crtl and Arrow keys.
The Universal Serial Bus Controller and Human Interface Device headings should disappear completely from the Device Manager. Before rebooting to Windows Standard Mode, insert the Windows CD into the CDROM drive and direct Windows to look in, (Example D: / Win98, where D is the letter of the CDROM drive on your system), Win9X folder on the CDROM when/if prompted.
UNPLUG ALL USB DEVICES BEFORE BOOTING TO WINDOWS
USB Does NOT like to share it's IRQ with another device especially when the user is employing sophisticated USB peripherals. Even though Windows may report NO conflict, if USB is sharing its IRQ with another system peripheral, (i.e. video, sound, SCSI etc.), that is often the source of the problem. (IRQ Holder for PCI Steering is NOT considered another device)

Hi Pete,
hope you had a nice weekend. I did ask the guy who installed the new XP for me if he had moved the card, but he could not remember, so on the weekend I will open the case up and move the card to a different slot. Just to see what happens. Should I uninstall the drivers before I do that, or will Windows sort that out itself. The only difference that I can really think off is my front USB1 hub used to be connected to the Mobo and now it is connected to the internal plug of the USB2 card. I can plug my USB Pen into it that is USB2 and it works ok no problems at all it is just the Canon 8000F Scanner that does not like it as it is.
Hard to figure out what the problem is.
