RE: code 39 keyboard win XP

Hi

Figured out how to fix this error if anyone is interested.

It is a bad Upperfilter setting in the registry.

To repair this error:

1) go to C:\Windows\System32\Regedit32.exe

2) Click on Edit -> Find

3) Type in kbdclass (be inventive here as I know you cant type. Copy this name from c:\windows\system32\drivers\kbdclass.sys - right click and click rename. Then just copy the 'kbdclass' - this can then be pasted in the regedit box)

4) Search through for as many Upperfilters you can find.

5) They most likely have 2 lots of drivers associated with it eg 'tphclhs kbdclass'

6) Double click the 'Upperfilter' and delete the other entry except 'kbdclass'

7) Search for all instances of this and change them

8) Go to device manager and uninstall your keyboard - then 'scan for hardware changes'

9) You will most likely need to restart

Keyboard should now be working fine.

I actually surprised myself in solving the error - as you normally delete the upper and lower filters for CD-Roms when they have the error code 39 - so I guess it would work for all devices that have upperfilters.

Worked for me so hope it works for you too.

Best of luck

Bas

RE: code 39 keyboard win XP

A big thank you to Bas13.

I had spent a frustrating week or so with this exact error on my work PC. I could only work using Remote Desktop from another machine in the office.

Anyhow after following the instructions from Bas13 and removing extra entries from my Upperfilter(s) My keyboard was operational again.

For the record (in case anyone else has this problem) my extra entries in the Upperfilters came from a VMWare (server) install.

I am not sure what went wrong with my VMWare install but that is what caused my keyboard to stop functioning.

No other fix had worked and I had tried:
- reinstalling drivers of Win XP CDs
- uninstalling and reinstalling VMWare
- going to numerous WinXP restore points
- all the usual registry fix tools

Anyhow thanks again Bas13.

RE: code 39 keyboard win XP

Kudos to Bas13! I was on the verge of wiping the system and rebuilding it, but this did the trick. Turns out that the software that killed my keyboard was "SAM2003." Didn't know it had done anything bad till a week later when a powerline glitch rebooted the PC, and the keyboard stopped working.

Brandon Moses on September 16, 2007
RE: code 39 keyboard win XP

I have the same problem but i see no other entries in my registry than the default and kbdclass. I can search for upperfiles and lowerfiles but my results are all associated with my CD-ROM drive which works just fine. What I don't understand is why this happened- everything was working fine until we had a power outage one day while i was using it, then when i turned my computer back on it would freeze if i pressed a single key. I would just have to reboot and use this on-screen keyboard.
ferni on September 19, 2007
RE: code 39 keyboard win XP

guys plz could u help me fix my keyboard plz bas 13 i can only see 2 typesof keyboards one just says default and the other kbdclass i have tried delteting that one but still it just cums up again and again and the other one that says default u cant delete help plz

Uninstall and then reinstall your device.

To resolve the problem that is causing Device Manager to show an error code for your device, try uninstalling and then reinstalling the device.

To uninstall your device

Open Device Manager.

If the category for your device is not expanded, double-click the category.

Under the category for your device, right-click the device that you want to uninstall, and then click Uninstall.

In the Confirm Device Removal dialog box, click OK.

Note

To open Device Manager, click Start, click Control Panel, click Performance and Maintenance, and then click System. In the System Properties dialog box, click the Hardware tab, and then click Device Manager.
Once you have removed your device, use the Add Hardware Wizard to reinstall it.

To reinstall your device

Close any open programs.

Start the Add Hardware Wizard.

RE: code 39 keyboard win XP

Bas's fix worked for me too! Just had to remember to continue to "find next" until all the baddies were dealt with.
I was also a victim of the VMWare.

Thank you very much Bas13. Your instruction helps and saves many time for troubleshooting.

RE: code 39 keyboard win XP

Thanks Bas13, siliconguide, and Google! I had this problem after uninstalling VMWare Player, and the instructions worked great for getting my keyboard functionality back.

Thanks!
Kevin on February 14, 2008
RE: code 39 keyboard win XP

The common factor with all the keyboard problems is using MICROSOFT REMOTE DESKTOP - which replaces the driver for functionality but does not replace with the correct host driver after use.
I keep full operating system backups using Partition Magic, and the only way out was to bin the ops system and replace with a copy of the Master Ops System Backup.
I am trying to find an alternative FREE REMOTE DESKTOP FACILITY.
Michiel on February 16, 2008
RE: code 39 keyboard win XP

The Solution of Bas13 also works fine on Windows Vista Ultimate(32bit) after deďnstalling VMWARE Workstation on my machine, my keyboard also didn't respond anymore with a code (39) in device manager. So thanx a lot Bas 13!
kop4 on February 22, 2008
RE: code 39 keyboard win XP

I'm a little confused on Bas13's solution.When i do the "find next" button with kbdclass i only get two things: (Default) and \Device\KeyboardClass0.

Both are type REG_SZ, and under data the default says (value not set) and the other says \REGISTRY\MACHINE\SYSTEM\ControlSet009\Services\Kbdclass.

Any further assistance would be greatly appreciated.

RE: code 39 keyboard win XP

thanks to bas13

note: you can also double-click on:

c:\windows\system32\osk.exe

which start a virtual keyboard, if you click on the letter 'A' for example, it's like you type the 'A'

RE: code 39 keyboard win XP

I fixed this with some registry editing. TO make it easier I also created a REG file that should work: http://personal.ryantadams.com/2008/01/18/keyboard-not-working-due-to-missing-or-corrupt-drivers-code-39/

RE: code 39 keyboard win XP

Hi, I couldn't find anything other than 'kbdclass' under any of the upperfilters. I'm not sure but it may have been because I tried a similar solution to this earlier which I found on a few other sites:


Click Start
>type in the Search box “Regedit”
>Click Hkey_Local_Machine
>System folder
>CurrentControlSet
>Control
>Class
>4D36E965-E325-11CE-BFC1-08002BE10318

-Click to select UpperFilters in the right pane, delete it
-Click LowerFilters in the right pane, delete it

Close Registry window and restart the computer.

(My keyboard still did not work after doing this, however)

Thank you for your help.

creaturex on May 3, 2008
RE: code 39 keyboard win XP

Ok, for everyone struggling with BAS13's explanation, I'll try to explain it in a simpler manner. First, for simplicity's sake, open up the on-screen keyboard in Start->All Programs->Accessories->Accessibility->On-Screen Keyboard

Now, open the Start menu and click Run. In here, type "regedit" and hit enter (on the nifty on-screen keyboard, of course.)

Once there, click Edit at the top, then click Find. Type kbdclass and press find. Now, look at the key it found. If it is named Upperfilter or Lowerfilter, then that's one of the ones you're looking for. If not, press f3 (find next) on the on-screen keyboard, and wait for it to find another. In my repair, I found kbdclass about 20 times, but only 4 of them were the keys I was looking for. Now, when you find one named Upperfilter or Lowerfilter, look at the contents of the key, mine, for example, read "kbdclass vmkbd". If it says anything besides "kbdclass", then you need to fix that key. Right click it and click Modify. From here, delete everything except "kbdclass", and save the changes. You should have to modify a few of these, or maybe even just one. Just make sure you search through the whole registry, by hitting f3 until you get a message saying "Windows has finished searching the registry." Then do the uninstall and reinstall like BAS13 said, and you should be set. I didn't even have to restart, but that doesn't mean you won't have to.

By the way, my issue was caused by VMware (uninstalling, to be specific)
grable on May 16, 2008
RE: code 39 keyboard win XP

Thank you Bas13!!!

This solved my problem perfectly, and uninstalling VMWare was the culprit on my machine as well.

Thanks again :)

RE: code 39 keyboard win XP

Hi,

Having this problem as well and the fix works great, i'm having the problem on multiple machines so need to establish what has caused the issue. How did you identify that VMware was the culprit?
