I have an annoying issue.
My NUC is disabling the USB port if I leave my USB harddisk attached when shutting down. That means that it will not find the disk after startup (but it gets power, as the power-indicator on the drive is on).
The only way I can re-find the harddisk is to attached to another USB-port. Then it runs again.
The USB port remains disabled untill I cut the power to the NUC completely (remove the power cable).
It can not find drives attached in BIOS/boot-disk mode either, pointing to a hardware/bios problem rathern than a windows-issue.
I have tried to:
- update USB drivers.
- update BIOS
- change different BIOS settings related to USB drives
- other harddrives
- flash-drives
- disabling the power-save settings for USB
Nothing works. If I leave the USB drive attached during shut-down, the port is disabled untill I remove the power-cable.
I have a mouse/keyboard attached also. They work fine.
I have a monitor with USB-ports attached also - that works fine (but not if I attach a USB-drive!).
I have a camera that I have attached also - that works fine.
It only seems to be related to hard/flash-drives.
Any ideas what is causing this?
