USB ISSUE

I have a Toshiba Satellite Pro 6100 with a clean install of Win XP SP2

I am getting the following error message in a small window appearing from the system tray.

usb device not recognized.
One of the usb devices attached to this computer has malfunctioned, and windows does not recognize it.

This issue being is that I don't have any usb devices attached to my machine?

The only way I have found to resolve this issue is to disable the devices in Device Manager, this is far from ideal.

The usb devices don't make any sense either. There are 3 usb host controllers listed but I only have 2 physical usb ports?

The device drivers for your laptop may need to be reinstalled, because the ones on the WinXP disc may not work properly.  You can usually get them from the manufacturer's website.

I would go into device manager and uninstall all devices under universal serial Bus Controllers then reboot the laptop and let them all reinstall and see if the problem then goes away. If not then click on the host  controller and see if it can find an updated driver.

Install the chipset drivers or USB drivers if provided in chipset link and perform a Windows update. After performing the steps, reinstall the drivers for the USB.

Yes, that was the first thing I tried.

To add some more information: this issue consistently occurs immediately after the laptop comes out of standby mode.

As mentioned above, Device Manager lists 3 Host Controllers and 3 USB Root Hubs.

I still have no idea why 3 as apposed to one.

If I look at each of the 3 USB Root Hubs after the machine has come out of standby and look at the Power Tab two Unknown Device's are listed for no apparent reason.

3 Root hubs each with 2 unknown devices equals 6 devices that the laptop is complaining about. This directly corresponds to the number of times the balloon displaying the error message appears.

This must be to do with the stand by mode - possibly to do with power?

I have tried uninstalling and reinstalling the drivers a number of times. This clears the mystery devices but they then appear again after coming out of standby mode.

The devices appear as follows in device manager:

Universal Serial Bus Controllers
      Intel(R) 82801CA/CAM USB Universal Host Controller - 2482
      Intel(R) 82801CA/CAM USB Universal Host Controller - 2484
      Intel(R) 82801CA/CAM USB Universal Host Controller - 2487
      USB Root Hub
      USB Root Hub
      USB Root Hub


I have no idea what the numbers at the end of the host controllers mean - or whether this is relevant?

Have you tried running the windows update?

if not go ahead and do so..it might detect what the problem is and fix it.

It's not a device - it's a built-in USB Host Controller, which is normal.

WatzmanCommented:
It's safe to day that the unrecognized device is the 3rd hub, which most likely is not recognized because the proper driver for it has never been installed.  If you have 3 hubs (note, this is not the same as 3 ports), then it's likely that you have some USB ports whose root hubs are not part of the motherboard chipset.

hi...
i have the satellite pro 6100
the DVD drive it's an usb device... may be this is the 3rd one....
it works good?

i don't think its a bios version the point becouse this is an old laptop and it worked before you made this clean install (i suppose)
but update it's always good... and may be they changed something that fix the problem....
what do you mean with clean install? have you installed from the manufacter DVD? or from a WindowsXP install disk?

becouse of Toshiba use to trick some driver for let it work with your laptop and a clean install from a windowsXP install disk may not have some "important" trick.... (i know it becouse of some issue when try to update my graphic card with a NOT Toshiba driver working in every other GeForce2 GO like mine and yours...)
why don't you install from the manufacter DVD and then upgrade to SP2?
if you don't want to do this may be very difficult to find a solution.... (if im right)

hope this help..
bye...

USB has a lot of known problems with USB since u mention speciically that this problem comes during standby mode when the USB is not able to reinitialise properly.


You can try to disable USB power management in the BIOS so that it doesnt power down. It wont do much harm probably expend a little more power during standby but nuthing more.

Check here if u can find a solution for ur problem : http://www.usbman.com/winxpusbguide.htm

Do u have any wireless device attached to the system? Try working without that and see if it helps.

Read here for a possible solution to ur problem. : http://support.microsoft.com/default.aspx?scid=kb;en-us;822603

Ok, here is some stuff that I've tried so far.

No joy with Windows Update

Updated the BIOS

Installed the Intel Chipset drivers

There is no option to manage USB power in the BIOS but in Device manager I have unticked the "Allow windows to turn power off for this device, etc"

I Read that microsoft article  - the download they suggest is pre SP2 though

I have disabled
     Intel(R) 82801CA/CAM USB Universal Host Controller - 2484
     Intel(R) 82801CA/CAM USB Universal Host Controller - 2487
They didn't seem to do anything at all, the DVD drive is still functioning so I have no idea what those host controllers are for.

So I now have one
Intel(R) 82801CA/CAM USB Universal Host Controller - 2482
And one
USB Root Hub

This narrows things down a bit.

I don't think it is a driver issue because usb devices work fine when they are connected.
The issue only occurs after coming out of stand by, it must be power related I think.

In device manager if I click on USB Root Hub and click on the power tab it currently shows
2 Ports available - power required 0

This represents the two USB ports available on the back of my laptop. I have tested this theory by plugging in USB devices. They appear listed on this tab when they are present.

Even if it says 2 Ports available before going in to standby when I come out of stand by 2 phantom devices have appeared both of which are listed as "Unknown"

At the moment my only option is not to go in to stand by mode - which isn't really an option!

i think your usb is dead, and there is nothing you can do

mastrominchioneCommented:
but... from where do u install (Toshiba installation disk or Microsoft?)
USB it's not dead... becouse of the issue come later return from stand-by... this mean something goes wrong when it reactivete the power to the usb...
may be hardware but i think it's software issue.. becouse:

like i said... when i install the NOT toshiba driver for my graphic card 1 of the problem was that when i return from stand-by my monitor don't light on any more.. the when i reboot it's all ok!
there was other 3 prob... i solved all this by changing something directly in the INF file...
may be it's the same....
when it start to do such a thing?
don't use stand-by it's not a solution...
you can try to set in the device manager not to permit unplug the power when in stand-by mode... but either this isn't a really solution...
this can tell you if the problem is really reconnect the power to usb or not. you said that u done it and never changed.....
and that let me think it's really not an hardware issue...

i repeat again my question... from where do you install?
if the issue it's here we know what to seek....

It was a clean install from the Win XP CD

I have now solved the problem...
I thought I'd tried this earlier but apparently not

In device manager, root hub properties, power management tab, untick allow computer to turn off this device.

-In device manager, root hub properties, power management tab, untick allow computer to turn off this device.

this mean some trouble in restoring power... this is for shure driver issue.....
and it's not a solution.... it don't show you that annoiyance any more but it don't work perfectly...

trust me.. it's becouse you install from win XP cd instead of Toshiba recovery DVD....
if you are actual happy take it that way :)
next time install from recovery DVD and than update from windows update if you don't want this issue
bye!
