USB Problem. Driving me nuts!

I think this was already covered, but just in case: Tips for solving problems with USB devices

Are there any events in the event log showing error codes?

Are there any conflicts in Device Manager - you might want to view hidden devices (view menu), although most are legacy drivers. I had some 'ghost' devices once - they'll show up grey. What to do about ghosts? I personally don't believe in ghosts, so I backed up my registry and deleted the extraneous entries in device mgr. Did that fix my problem? Nope, the DVD drive truly was bad and had to be replaced. But the ghost entries were created when I tried to fix the DVD without actually replacing the hardware.

edit: Uninstalling and then reinstalling the drivers for the device is a likely solution to a Code 10 error.

Important: If a USB device is generating the Code 10 error, uninstall every device under the Universal Serial Bus controllers hardware category in Device Manager as part of the driver reinstall. This includes any USB Mass Storage Device, USB Host Controller, and USB Root Hub.

Note: Properly reinstalling a driver is not the same as simply updating a driver. A full driver reinstall involves completely removing the currently installed driver and then letting Windows install it over again from scratch.

Peace!

Did a search for a downloadable mpfilt replacement and got a solution on social.technet.Microsoft.com/forums translated from a Chinese site

"""""""""""Firstly, You go to the folder \Windows\syswow64\drivers and delete this file mpfilt.sys . then restart the computer.

after that open up the regedit editor (enter 'regedit' in search box) . and then go to HKEY_localmachine\system\currentcontrolset\services\mpfilt , then delete the "mpfilt" folder.

Do the same to these two key also ...HKEY_localmachine\system\controlset001\services\mpfilt and HKEY_localmachine\system\controlset002\services\mpfilt

. then go to this key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36FC9E60-C465-11CF-8056-444553540000} and delete the value "Lowerfilters " .
do the same to HKEY_LOCAL_MACHINE\SYSTEM\controlset001\Control\Class\{36FC9E60-C465-11CF-8056-444553540000}
and HKEY_LOCAL_MACHINE\SYSTEM\controlset002\Control\Class\{36FC9E60-C465-11CF-8056-444553540000} .
..

then it's finished """"""""""

seems this also works for mouse and other peripheral problems, too.

I will try it and let you know. Thanks for your help, especially Slarty as checking the Events log identified the cause.

I'm running win7 x64 homeprem - did a search for mpfilt.sys - not found.

you beat me to the registry check - cool!
hope the fix you found works.

edit1: you might want to rename files/folders instead of delete.
although sometimes Windows is too smart and follows a rename.

edit2: controlsets - check for any numbered controlset (001, 002, 010...), as well as current

edit3: I always forget about those handy event logs too. Wish I understood what they said.

Peace!

Glad it worked.

Filters on HW seem to present problems...sometimes. I chased down a "DVD not recognized" issue a while back. MS Mr. Fixit modified upper and lower filters. Unfortunately that did not solve my DVD problem. Each HW issue will be different - some filters are valid, some present problems. Good work on finding the fix, all you needed was to be pointed in the right direction - something we all need from time-to-time.

What state did you leave your USB drivers (and don't say I'm not in the States). You know where I'm headed with that.

Peace!

Final thoughts.

1. The stick might not be defective, it just has unnecessary install crap on it.
   The capacity well... buyer beware
2. Control Panel ==> Autoplay - change default actions to prevent unexpected installs
   I disable it for all devices, but you can choose what's best for you.
   Disabling autoplay means you will have to manually launch what ever is on the device. Without autoplay, you have the option to explore the device before the system takes action. Big deal, I have to Dblclick audio CDs, or launch a player. Far better than chasing down a device 'error'. The thing is, if you're used to autoplay, you might think "Hey wait-a-minit now my audio CDs won't play". Perhaps you'll remember (6 or even 12 months from now) that you changed autoplay and how to change settings to suit your preference.
3. If you're strong enough ) - disable autoplay and explore the stick - delete what's on it or format it. You should now have a useable, albeit small, stick. If it's not worth the trouble, forget I mentioned it.

Thanks dad, I knew we'd make you proud some day!

A good call, both of you.

Peace!

1. Navigate to C:\Windows\syswow64\drivers
   
   • rename mpfilt.sys to mpfilt-USBerror.sys
   • restart your machine
   
   
2. Launch RegEdit
   
   • Start Menu ==> run ==> regedit
     Note: You can also launch RegEdit using the Start Menu Search box ==> regedit,
     then DblClick regedit presented in the search results
   • In RegEdit
     
     1. Navigate to HKEY_LOCAL_MACHINE\system\currentcontrolset\services\mpfilt
        delete the mpfilt key
     2. Navigate to HKEY_LOCAL_MACHINE\system\controlset001\services\mpfilt
        delete the mpfilt key
        
        Note: mpfilt might exist on additional control sets, check each controlset(002,003,010...)\services\mpfilt
        delete the mpfilt key
     3. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36FC9E60-C465-11CF-8056-444553540000}
        delete value "Lowerfilters "
     4. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\controlset001\Control\Class\{36FC9E60-C465-11CF-8056-444553540000}
        delete value "Lowerfilters "
     5. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\controlset002\Control\Class\{36FC9E60-C465-11CF-8056-444553540000} .
        delete value "Lowerfilters "
     6. Navigate to the top of the RegEdit window "Computer" (in regedit)
        Search for mpfilt - it is important to search only for mpfilt - you don't want to find mpflt or mpfilter.
        -> RegEdit Search: regedit edit menu -> select find -> enter mpfilt in the search box.
        -> Mark Checkbox labeled "Match whole string only"
        -> click "Find Next" button until you get the "Finished searching through the registry" message, Click OK
        
        If mpfilt was found when you searched, you probably just missed one. That's why you did the search.
        - make sure that it is mpfilt and the key is a service in a controlset, then delete the key
     
     
   • Close RegEdit,
     restart your machine, and you're done
