2 of my rear USB 3.0 ports are not working

I have the RS880 uATX 1.02 mobo (AMD 785G Chipset). I am having trouble with the 2 rear USB 3.0 ports - they are simply not working. Nothing I plug in there registers.. All the other USB ports work perfectly fine. It is just these two that are giving me problems. In a similar post to this one advice was given to download drivers for the USB 3.0 ports. Does anyone know what drivers I need to install for the AMD 785G chipset? Thanks.

  1. Is that a HP?
    download cpu-z, hit motherboard tab and post a screenshot here.
  2. Your motherboard dont have any USB 3.0 ports on it,
    that means you're having some problem with your USB 3.0 ports that are available on your Case ?
  3. I am having a bit of a hard time posting a screen shot on here for some reason, but I did download CPU-Z and here is the info I get under the "Mainboard" tab:

    Manufacturer: Foxconn
    Model: 2A92 1.01
    Chipset: AMD 785G
    Southbridge: AMD SB700

  4. GhostT_Hv,

    Yes, you are correct, my motherboard does not have USB 3.0 ports built in. The USB 3.0 ports are installed in my system by way of a separate USB card which is obviously attached to one of the PCI slots in the motherboard.
  5. then you'll need to install the drivers for your USB card.
    Which USB card do you have ?
    Did you get any driver's disc with your USB card ?
  6. I will need to take a look inside the case to see if I can identify the manufacturer of the USB card. My computer did not come with a separate disc for the USB card (it's an OEM computer from HP and they only gave me the system recovery discs - I have already installed Windows 7 a few times so I don't think the drivers are in there). I will get back to you on the name of the USB card manufacturer.

    okay
  8. The most common would be Renesas or Asmedia
  9. Ok, I pulled the USB card out and these are all the details I could see on it:

    On the side of the card that shows all the electronics it has a symbol that reads: PSC
    On the same side there is something that looks like a chip and it says: NEC Japan D720200F1

    On the flip side there is a label that contains the following details:

    Assy PN:607782-001
    SPN: 608151-001
    CT: PBGQD0AABZ20CE
    PN: RHA314-5 Rev. A

    On the green part of the same side where the label is, it also reads:

    CHI314PCB-2 Rev: 2.1
    USB3.0 Host Add in Card
    PCIe2 x1 10W + EXT 10W

    No where does it seem to show a brand name. Do you recognize any of these details?
  10. Is this your PC ?
    If yes then scan your pc and it will detect which drivers to update.

    There is one user named LarryMeBoy that gave a link to download drivers , check whether it is working or not.
  12. That's funny. I was just in the middle of reading that as well. Thank you for sending me the link. I will take a look at what information provided by LarryMeBoy. The more I read this the more I realize there must be a wire that is not connected correctly in the motherboard. Thanks again for your help.
