I too have an urgent need to disable XHCI via the BIOS.
This was a feature that was present in previous BIOS's but was removed for no apparent reason.
From the release notes for BIOS version 0025:
Removed [USB3.0 (XHCI mode) support] option from BIOS Setup and
enabled it by default.
Please can this be added back to the next BIOS ?
I have tried doing this a number of ways via software but cannot achieve it.
Is anyone monitoring this question?
Is there any possibility that the option to enable/disable xhci/ehci can be re-added to the NUC2820 BIOS ?
This used to be an option so I imagine would be easy to re-add and would not affect other users.
This is a major deal breaker for me, I have tried buying other devices (flatbed scanners) to resolve the issue, but the same issue exists (that would be resolved if I could disable xhci)
It's been a year by now. The Option still missing, though it's affecting quite some people. Can you please give some Information whether there will be something happening or not?
Seems a bit strange to me that an option that was already there and is common in most other bios is so hard to reactivate.
