    DX79SR hang at 5A with usb 2.5" sata hdd plugged in

    RobD

      This hang is 100% repeatable, but here's the wierd part. It does not happen if I also have my multi card usb flash reader plugged in as well, with or without a card in one of the slots. This is using the rear i/o black usb2 ports. Switching ports for the hdd doesn't make any difference.

      Also, If I unplug the usb card reader and instead connect a internal front bay card reader to one of the usb2 onboard headers, the hang still occurs.
      Uefi enabled or disabled in bios makes no difference.

       

      If anyone else can duplictate this issue, please post.

          Hello,

           

           

          We don't have any reports from other customers regarding this kind of issue. The problem you are experiencing could be related to a compatibility issue with the hard drive itself so our recommendation is testing with a different hard drive brand if possible to narrow the issue. You can also test the system out of the chassis to avoid any possible grounding.

            Hi  Dan, thanks for the reply.

            I think it more likely to be the controller in the enclosure. It's a Welland Sun Bright sata2 with esata as per this link

            http://www.welland.com.tw/html/enclosure/940.html

            The controller chip is a JM20329

            The hdd is a 500gb samsung, model HM500JI.

            The motherboard has only ever sat on a cardboard box. It has not been put in a case as yet.

              Hi Dan,

              Have tried this with another usb case and hdd. Result is still the same - hang at 5A

              Case controller chip is a ALi M5642

              Hdd is a 2.5" ide samsung 80gb model MP0804H

                Nailed it!!

                It's a conflict at post between my Logitech DiNovo Edge mouse/keyboard wireless usb dongle and the usb hdd.

                If I move the dongle to a internal header via a usb2 front i/o panel, the hang does not happen.

                If I move the usb hdd to an internal header with the dongle in a rear port, the hang does not happen.

                 

                Here's the weird thing though, if I leave the usb dongle in a rear port and plug in both usb hdd drives to rear ports, the hang does not happen, or - if I plug in one hdd to a rear port and a usb hub to another rear port, the hang does not happen.

                 

                The only configuration that causes the hang, is when only one usb hdd is plugged in to a rear port and the Logitech wireless dongle is also plugged in to a rear port.

                  This hang even happens with a usb pen drive in place of the usb hdd

                    I have stumbled across other combinations that also hang at 5A that do not involve a usb hdd or the DiNovo k/b - mouse dongle. In fact in these combinations, a usb hdd stops the hang. 

                     

                    I've been using a Digitech xc5146 hard wired usb k/b, a logitech v220 wireless mouse with matching c-uay59 dongle and usb sd/mmc card reader model ac- 6000

                    All three must be plugged to particular rear i/o usb2 ports.

                    Removing any one of the items = no hang

                    Adding a usb hdd to another rear usb2 port = no hang

                     

                    The arrangements that cause a hang are:

                    lan and 1394 are only included as reference to the port arrangement, nothing is connected to them.

                    'Hub' is the card reader

                    'Mouse' is the c-uay59 dongle

                     

                    lan          1394          lan

                    hub          -               -

                    k/b          mouse       -

                     

                     

                    lan          1394          lan

                    k/b             -               -

                    hub          mouse        -

                     

                     

                    lan          1394          lan

                    k/b             -               -

                    mouse     hub             -

                     

                    other arrangements that also hung were as per above but using the ports under the r/h lan port, e.g. as per below

                    lan          1394          lan

                    -               -               k/b

                    -               hub          mouse

                     

                    or using the upper middle port e.g. as per below

                     

                    lan          1394          lan

                    -               hub          k/b

                    -                 -             mouse

                     

                    Whilst I have not tested all possible combinations [I'd be there forever!!] it did seem that any other combination did not hang.

                     

                    Hoping this might help Intel hunt down the culprit!

                    edit: the dongle for the DiNovo wireless keyboard/mouse is a c-uv35
