Hi Chris,
Thanks for your patience whilst I was on holidays.
I see a driver version mismatch.
On the installation, you have 8.0 installed but not totally and the USB device drivers are still 7.9.
This is what I recommend:
1. Disconnect all devices using DisplayLink technology. I can see two (a Targus and Toshiba).
2. Do the installation clean-up as described in that article:
End User Cleaner. This will remove all DisplayLink files, registry keys and all.
3. Reboot
4. Download
DisplayLink USB Graphics Software for Windows 8.0 M3
5. Disconnect your computer from Internet not to get Windows Update interfering... Toshiba has not asked us to put 8.0 on Windows Update for their products.
6. Install the 8.0 you downloaded.
7. Connect the Toshiba dynadock when the installer asks for it.
8. Reboot, login and see if you've got displays working
9. Connect back to Internet.
If the issue persists, may you attach new logs so I can see the new status?
There is a manual way to change the USB device drivers, but that's a bit cumbersome.
Kind regards,
Alban
