Hi there,
I’m Filippo and i’m writing from Italy.
First of all, sorry for my english.
Than…I had the same problem. But recently I’ve updated all my pc’s drivers with this software: https://www.drivereasy.com/
[You can just install the free options]
Drivereasy ‘told’ me the my PCI drivers [and also the USB3.0 and 2.0 drivers] were old and not updated.
So, after some hours in front of my notebook, I get averything I need to use my mixpre-d.
Notes:
1) before any kind of new try with your SoundDevices, get all the drivers about PCI, USB, BIOS, Integrated AUDIO CARD and internal HD.
2) Go to your devices manager (with your mixpre-d connected) and unistall your mixpre-d.
3) disconnect the device, reconnect it and wait window’s installation response.
Let me know,
Filippo
