Hello Yves,
Tech support... <sigh> Why would Dell make a dock that doesn't support their flagship laptops?! If it was a Thunderbolt dock, I'd agree, but it's a real USB dock which even works on an Android phone.
From the logs, I guess you have tried a few things so we'll first have to clean up a bit. The many reboots are unfortunately necessary because Windows can't modify these drivers whilst running. We have some changes around that in the new Windows 10.
Here are the steps I advise:
- Disconnected the Dell D3100 and leave it disconnected until asked to connect it
- Remove 8.0.422.0 from Add/Remove program
- Reboot
- Run our Cleaner 8.0.422.0 and "Run as Administrator..." even if your user is an admin.
- Run our Cleaner 8.0.422.0 and "Run as Administrator..." again as the beta cleaner has a bug currently being fixed.
- Reboot
- Install 7.9 M7
- Connect the Dell D3100 when asked.
- Wait for the device drivers to be associated by Windows.
- Reboot
- Gather new logs with the Customer Support Tool so I can check everything is peachy.
Kind regards,
Alban
