USB-devices not showing in Explorer

ISDNO used Ask the Experts™
The Toshiba laptop in question has the following problem.
1: If you connect _Any_ usb storage device (Like a usb pen) the WinXP os will make all the "correct sounds" and it will list the storage unit as a "Usb mass storage" in the device manager. However it does not show up in Disk Management and not in Explorer.
2: If you connect an iPhone the iPhone will start charging so the USB-connection seems to be fine.

I have tried cleaning out any non-essential disk in Reg\HKLM\System\MountedDevices, I'we tried Uninstalling everything under USB (Including 0 hidden) via Device Manager.

Eventlog error1 and 2 included (Eventlog's in a foreign laguage, so ill try to translate):

For what it's worth iwe tried unplugging/rebooting/checking Disk Management several times (This is usually the problem when i come across this problem).

Thanks in advance.

Did you try reinstalling the USB drivers?


The computer is a Lifebook E8410, not a Toshiba.
Iwe searched FUjitsu Siemens's webpages using the Serial of the computer but cannot find any USB related downloads. As I write in my first post i have tried letting the OS find the USB-devices "from fresh" by uninstalling them. Am I missing something here?

try these :
-update your chipset driver, from the FUjitsu Siemens's webpages
-Remove old hardware devices :
go to Start>right click My computer>properties>device manager
in the view tab - click : "show hidden devices"
inspect  device manager for all hidden devices, and remove them


OR :
Remove all USB drivers with:      ---> Now reboot and test.
Delete the "UpperFilters" and "LowerFilters" registry values from:

you can also reset the usb :
rundll32.exe setupapi,InstallHinfSection DefaultInstall 132 C:\WINDOWS\inf\usbstor.inf
rundll32.exe setupapi,InstallHinfSection DefaultInstall 132 C:\WINDOWS\inf\usb.inf
rundll32.exe setupapi,InstallHinfSection DefaultInstall 132 C:\WINDOWS\inf\usbport.inf
rundll32.exe setupapi,InstallHinfSection DefaultInstall 132 C:\WINDOWS\inf\usbprint.inf

Check in Disk Managment what letters are assigned to usb devices after you plug them in. Maybe the system is assigning the letter which is already in use. In this case just change the letters.


I have now tried Nobus's tips (The "OR" part with the downloadable)
I ran  RenewUSB and rebooted. No luck.
I ran RMHIDDEV and rebooted. No luck.
I did not find any Lower- or UpperFilters' values in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36FC9E60-C465-11CF-8056-444553540000}
I then resetted the usb and rebooted.

Still same problem :(

what avbout trying the upper part ?


I'm sorry I completely ignored the part with Chipset Drivers.
Will try this now (Newer version is not avaiable but will try to reinstall)
Does the RenewUSB do "the same" as "Remove old hardware devices" manually via the device manager?
Either way I will check and uninstall any hidden device.


Tried to install Chipset Drivers from both FujitsuSiemens and directly from Intel - the installations finished up fast and neither of them solved the problem after a reboot. The computer did not have any hidden usb devices.

However, as the computer is generally slow and the user is going away on holiday I'll reinstall windows. Will let you know if that doesn't solve the problem. Thanks for all the help!


Even tho this did not solve the problem it's a solid guide to troubleshooting usb-problems.
