DX79TO: USB3 Hub-Problem and/or Bios Maintenaince Problem

Hello,

I've bought a new monitor: a HP Z27i, that has an integrated USB3.0-Hub;

(http://h10010.www1.hp.com/wwpc/pscmisc/vac/us/product_pdfs/HP_Z27i_Datasheet.pdf http://h10010.www1.hp.com/wwpc/pscmisc/vac/us/product_pdfs/HP_Z27i_Datasheet.pdf)

when I plug in the USB cable into one of the two USB3-Ports on the rear,

the operating system (Windows) detects a 'Renesas Electronics USB 2.0 Hub' and doesn't function anyway;

when I plug in the USB cable into any USB2.0-Port,

the operating system (Windows) detects a 'Generic USB Hub', and everything works fine,

but only with USB 2.0 speed ...

(would there be a workaround like this: installing another USB 3.0 controller into a PCIe x1 slot

with a different chipset - I tested this USB 3.0 hub on my other computer that has a different USB 3.0 controller on board and

detects a 'Generic USB Hub' as expected)

the other problem, when I power on the computer there isn't shown any start screen

(Intel logo plus the menu keys - F2, F9, F10, ...)

the graphics card is the same as before, the only difference: before the old monitor was connected

with a Single-Link-DVI cable and this new one is connected with a Dual-Link-DVI cable;

please can someone help me for a solution on how to get the start screen back;

Thanks,

 

Walter

Hello Walter, the behavior you are experiencing could be a compatibility problem between the Board and the USB3.0 of your monitor. I suggest you to install the latest USB3.0 driver available for your motherboard and test a different device on it just to verify if it is working as expected. https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=19880 Intel® Download Center

You may test a regular 3.0 flash drive, and check if it is running at that speed.

Regarding the issue with the start screen, I would recommend you to do a clear CMOS on your board.

  • You can also test another monitor
  • Check the TV or monitor source is HDMI, VGA or DVI, depends on the video card you are using.
  • You can try doing a BIOS update. If the current BIOS version is the latest one available, you can try to reinstall it. https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=23825 Intel® Download Center

Hello,

I'm already using this latest USB 3.0 driver and my USB 3.0 flash drive runs with about 150 MByte/sec - the expected speed;

how can this compatibilty problem between the Board and the USB 3.0 of the monitor be solved?

my video card is a nVIDIA Quadro FX 380

(http://www.nvidia.com/docs/IO/68254/NV_DS_QFX_380_US_Mar09_FINAL_LoRes.pdf http://www.nvidia.com/docs/IO/68254/NV_DS_QFX_380_US_Mar09_FINAL_LoRes.pdf)

the monitor I had before (a 24" HP with 1920x1200) showed the start screen;

how can this be influenced whether this is shown or not?

is the CMOS cleared by the jumper on the board that is put the other way for a short time?

Thanks,

Walter

Walter, we tried to make as many third party components compatible as possible, but do to the sheer quantity of these third party components we cannot always guarantee compatibility. I suggest you checking if you are maybe missing the USB 3.0 drivers from the tv.

Regarding the CMOS, please follow these instructions. http://www.intel.com/cd/channel/reseller/emea/eng/membership/411560.htm How do I clear the CMOS?
