How to delete vmulti device?

GoogleCodeExporter commented 8 years ago

What steps will reproduce the problem?

Build and install vmulti.inf with devcon.exe. Then try to do "devcon remove 
hid\vmulti" and the device seems impossible to remove ("Remove failed"). There 
is also no "disable" or "uninstall" option in Device Manager. How do I force 
vmulti to be removed?

Thanks for any help

Update: I removed it by booting into safe mode. Would still like to know if 
there's an easier way.

This has always worked for me

There is in my case, sorry I am not sure what went wrong in your situation

No worries. After some experimentation I think that it's due to one of the 
device nodes the default vmulti install creates. My best guess is that one of 
them somehow becomes in use and un-removeable so Windows refuses to uninstall 
hid\vmulti.

In any case rebooting and/or using safe mode seems to fix the problem.

Thanks for your response.

Anyway, this issue can be closed (I don't see where I can close it)

cheers, 

it could be the tablet pc service not letting go of a handle, next time try 
killing it (wisptis.exe) and then uninstall

Actually I'm in the same situation.

I cannot remove the device in the hardware device manager and devcon remove 
fails as well. The only way to proceed is to reboot in safe mode and even then 
I can only rename the driver files (still no remove available, devcon still 
fails) and delete the devices on _another_ reboot.

That makes iterations slow, of course. Do you have any idea where I could look 
for the culprit here? I tried stopping the tablet input service/killing 
wisptis.exe (it's respawned right away) but there's no difference. I can remove 
all device nodes ("HID compliant game controller" for example) _except_ for 
"VMulti HID". Context menu only offers "Update driver software", "Scan for 
hardware changes" and "Properties" on that node.

I have this issue on two totally unrelated Windows 7 (32bit) VirtualBox images. 
What is different on your system?

I have had good luck running the command: devcon.exe remove *vmulti*

This removes all of the subdevices and root devices associated with vmulti. 
Usually it will fail for one or more devices on the first run, but on the 
second run gets everything left.

Thanks for djpnewton, I can easily finish my job using vmulti.
I once met this problem before, it due to I append keyboard HID descriptor.HID 
key board device can not be disabled, it is "under custody" by windows. So you 
can't uninstall your driver, the "disable" or "uninstall" option was gray.If 
you want to remove the driver, you should first uninstall HID keyboard device, 
then the "disable" or "uninstall" option can be used again.
I hope it will be helpful.
