I have an AC 7260 Mini PCI-E module in my NUC. It was working fine until today (for about 6 months).
Today I started a driver update session, and after updating the BT driver to the latest 3.1.1311, I get a Device Descriptor Request Failed error.
The Wifi still works fine.
I noticed some resolved issue with a bad batch of cards, but it can't be that since my module worked fine for several months.
Any idea what could be the issue? Or is it just dead?
I tried an older driver, didnt help.
Ok, rolling back an even older driver did the trick.
Installed 3.0.1304 and all is well again.
