Microsoft Teredo Tunneling Adapter

Topic

New Reply

I have a problem with 2 USB drives which I use for back-ups. When I plug them in there’s the usual ker-plunk sound, then nothing. In Device Manager there is a yellow exclamation mark beside Microsoft Teredo Tunneling Adapter, and the device status is “This device cannot start (Code 10)”.

Searching for an updated driver brings up “The best driver for your device is already installed.”

Anyone know how to get out of this hole?

Thank you for that, but I have no idea what a BBCode is.

H0wever, further to Tunneling Adapter, I found an exclamation mark beside the laptop icon in Devices and Printers. Trouble shooting brings up “There is a problem with this driver…” and offers to re-install it. “Apply this fix” doesn’t fix it.

Those are 2 separate issues. The Microsoft Teredo Tunneling Adapter is a networking protocol that just makes it easier to get to websites irrespective of whether they are using IPv4 or IPv6 addresses. It does the translation so you don’t have to.

The USB issue sounds like Windows recognising the insertion of a USB device (the ‘de-dunk’ sound) but failing to enumerate its capabilities, i.e. “I know it’s a USB device… but what type of device is it?”. This may be due to a long-standing bug in Windows whereby it sometimes gets confused if the USB history list (stored in the registry) grows too long or becomes corrupted.

Try this:

1.. Disconnect the 2 troublesome USB drives.

2. Download/unzip Nir Sofer’s USBDeview. (Note that there are 2 versions – 64-bit and 32-bit – so make sure you download the version that is the same ‘bitness’ as your version of Windows.)

3. In the un-zipped folder, *right*-click on the usbdeview.exe file and choose Run as administrator then accept the User Account Control prompts that asks if you want to allow it to make changes to your PC. This will give USBDeview the elevated rights it needs to remove USB history information from the registry.

4. Reconnect both troublesome USB drives. Do they show as connected and get a drive letter assigned?

5. If they are still not recognised, use SHIFT+click to select them both in USBDeview then, in USBDeview’s File menu, choose Uninstall Selected Devices.

6. Disconnect the 2 USB drives and reconnect them. Let us know what happens.

Hope this helps…

Maybe this thread, https://www.askwoody.com/forums/topic/teredo-tunneling-device-stopped-working/ will help you?

Good luck!

Thank you both for your responses. I’m going to try to resolve the USB issue first because I haven’t had any problem with Websites…yet, and it’s time for a full back-up.

Will post the result.

Thank you both for your responses. I’m going to try to resolve the USB issue first because I haven’t had any problem with Websites…yet, and it’s time for a full back-up.

I just installed and ran USBDview. Immense amount of information, most of which is beyond my limited intelligence. However, the 2 drives were recognized, but did not have drive letters. I uninstalled both, then removed them. When I plugged them in again they were assigned as D & E. Looked good, so I opened File Explorer; they were not listed. Went back to USBDview, now they were recognized, but without drive letters.

Incidentally the drives both work normally on another machine.

I’ve seen cases where the drive letter that the OS want’s to assign to a USB Storage device conflicts with another drive letter.

With the devices inserted:

Open Disk Management.  Look for Disks with partitions that do NOT have a drive letter.  Right click on them, and try to assign an UNused drive designation.

If you see your C: drive listed right beside non-drive letter partitions, please ignore those – they are special OS data partitions for booting and system restore – you’re looking for a disk that usually has just one partition on it, and that one might be missing a mountable drive letter.

Good luck!

Which solution worked? It’s not clear.

Sorry for the ambiguity. It was the USB drives problem that has been resolved, so I have my back-ups back. Now I need a rest before I tackle the even more abstruse Tunneling Adapter issue. Will post when (if) I I sort it out.

So, it was the USB drives problem that was resolved – good! Now please make it clear which solution worked for you to resolve this…. then perhaps we can move on to the Teredo issue.

The solution that worked was assigning drive letters. I didn’t want to assign the original letters, didn’t know if that would [mess] things up, so I used letters that definitely had not been assigned. Once I did that the drives appeared in Windows Explorer. However, the previous back-ups were no longer listed in Easeus. Next step was to assign the original letters and that worked.

Great – Thanks for clarifying.

Have a look at this Microsoft Teredo Tunneling Adapter not working post. The first solution worked for me so I made a note of it.

Hope this helps…

Thank you Rick, I worked through the instructions step by step. Finally had to delete the adapter, but that did it. No warning flags now, and I have that link safely tucked away for the next time.
