    HP AIO Pegatron IPISB-NK

    Hi,
    this AIO boot with blue screen asking for "Press the ESC key for Startup Menu".

    The problem is that doesn't work any of its usb ports, so keyboard is not detected.

    I've tested another bios pch-dump but doesn't solve. (the same blue screen)

    I think it is a problem with pch, but I would like to check the ec-bios before going any further.

    I have read this chip and attached its contents just in case someone can test it or share a good one.

    Thanks in advance.

          Thanks SMDFlea,

          this is one of the dumps I've already tested.

          Same problem with usb ports, tha's way I asked for a dump for ec- bios.

          Kbc chip is an IT8519e.

            I don't have the ec. It won't help anyway the problem is somewhere else, a USB controller chip,if there is one,or the PCH.

              Thanks for being interested in this post, you are are always helpful.

              I think there is not a usb controller chip, so most probably is a pch related issue.

              I will let you know how it is solved finally. ( if owner wants to repair it)

                Hi SMDFlea, you were wright, there are a damaged usb3 controller chip.

                It is a Texas Instruments TUSB7320, and as I said it is damaged and blocks the other usb2, that I think that sre controlled by the pch.

                I removed the TUSB7320 chip, and except usb3, all is working properly.

                I hope this post can help someone else to solve other similar issues.

                Thanks for your help.
