Hi Sylvia. To do the complete test, you need to start up Windows 7 - attach the harddrive - let it be recognized - and then shut down the NUC with the harddrive attached. Then - when I try to start up again, with the harddrive still attached - it is not recognized. If I unplug it a and reattach it, it is not recignized - not untill I have completely powered off the NUC:
I use the two USB-ports at the back of the NUC (same side as the power-cable). I have not tried with the two at the front (since my keyboard and camera are hooked up there).
The USB-disk is e.g. WD My Passport Ultra 2 TB R/N D8B and the flash-drive a Sony MicroVault 1 GB. I have tried seveal others also - same result.
Allan / "Koraltop"
i have the same problem of Koraltop. I have model D34010WYK.
I connected a Document Camera (Hovercam Solo8) and an Hard Disk (Buffalo MiniStation 3.0) on the USB at the front.
The NUC recognize the devices and everyithing works great.
When i shutdown, The USB port remains disabled untill I remove the power cable.
If i restart Windows 7, the system recognize the Document Camera and the Hard Disk.
Could you help me?
Guys I’m going to try to replicate this issue again. Please send me the following information
- NUC model number
- BIOS version installed
- USB driver installed
- Operating system:
- Peripherals you are using:
When did you start getting this behavior?
Was there any change on the system configuration?
Any program or update installed?
NUC: D54250WYK - manufacturing date 10/2013
Bios: WYLPT10H.86A.0030.2014.0919.1139 - have updated at least twice - issue was persent also before that.
USB 3.0 driver: 184.108.40.206 - have tried searching for newer driver. None found.
Operating system: Windows 7 Home Premium 64 bit Danish. Fully patched.
- Logitech MX3000 usb keyboard and mouse in front USB port
- DELL U2412M monitor with USB hub (issue present even if this hub is removed)
- periphericals attached: Logitech camera (issue present both with and without camera)
- LogiLink USB card-reader
- WD 2 TB external USB 3.0 disk (experiences the port disabelling if not detached before shutdown)
I have had the behavior ever since I started using a USB-disk. No update og installation of periphericals identified that could have caused the issue. I have tried removing all hardware I could think of to get rid of the issue. No cause or change found.
I updated the bios. It had the same effect as cutting power - and the disabled lower back USB port functioned again after update. Unfortunately, it cuts off again after shutting down the system and restarting it with the WD drive attached - i.e. the update had no effect on the issue :-( The problem remains.
