Solved Add 2nd USB PCI-E addon card to mobo - good or bad idea?

September 6, 2016 at 06:33:10
Specs: windows 10 x64
Hi, in my pc I currently have a usb 3.0 PCI-E addon card installed and running fine, would it be possible to add a second usb addon card, this one usb 2.0 PCI, without any conflicts? OS is win 10 64bit. I need more usb ports as 2 on my mobo have died and I use several usb devices at once. I do have a free PCI slot.

I would suggest you remove the add in card. Then Install the chipset and all the USB drivers from the Gigabyte site. Then go into Device Manager and remove all USB listings. Disconnect ALL non-essential USB hardware. Then reboot and let Windows install the chipset and USB drivers. After Windows finishes, go into Device Manager and verify all USB ports are working properly. Finally, try connecting your USB hardware, one at a time. If something doesn't work after that, then verify the correct drivers are installed.

You have six additional USB ports that work off motherboard headers. You need to install breakout brackets with USB ports on them in empty slots in the back of your case. If you have any questions about any of this, do not hesitate to ask.

There is no reason you should need to use an add in card with that motherboard.

Instead of another card, I suggest a powered usb hub. Check this out.

Did you verify the USB ports are dead? Look in device manager to see if they show up there.

Post the FULL model of your computer, or the motherboard model.

Gigabyte GA970-Gaming mobo rev.1 BIOS F2
FX-8350 cpu
16GB 1866mhz Kingston Hyper-X (2x8)
Corsair RM850 850W PSU
EVGA GeForce GTX 970 SSC
256GB Plextor m.2 SSD (boot drive)
240GB Kingston SATA III SSD (run games off this drive)
1TB Seagate SATA III 7200 rpm (storage)
2TB Seagate SATA III 7200 rpm (storage)
Rosewill USB 3.0 pci-e 1x addon card
3TB Seagate External USB 3.0 hdd (backup)

No errors or anything unusual in device manager. All drivers installed, latest available. Win 10 pro X64 updated to latest version. Its the 2 USB 3.0 ports on the rear of the mobo that are not working. Ive tried several devices in the ports, Windows recognizes and installs the drivers for the particular device, but the device will not function. Example: my webcam is detected, shows up in device mgr but does not work when tried in Skype and several other apps. My external hdd will run very slowly if plugged in these ports, as in 20-30 mb/s. My game controller is recognized in windows but will not work in games that it previously did. It sounds like a driver issue but Ive triple checked the drivers, uninstalled and reinstalled, and about 3 weeks a go I did a clean fresh install of win 10, same issue.
In device mgr under USB section I see a VIA USB 3.0 eXtesnsible host controller...I assume this is the USB 3.0 ports on the mobo? The addon card uses a Renesas chipset. No changes were made to any BIOS settings.

According to the support website there are a large number of USB ports available:

South Bridge:
12 x USB 2.0/1.1 ports (6 ports on the back panel, 6 ports available through the internal USB headers)

VIA® VL805 chip:
4 x USB 3.0/2.0 ports (2 ports on the back panel, 2 ports available through the internal USB header)

ASMedia® USB 3.1 Controller:
1 x USB Type-C™ port on the back panel, with USB 3.1 support
1 x USB 3.1 Type-A port (red) on the back panel

Is this what you experienced?? Win 8 and Win 10 are nearly the same.

I suggest to check tis first if not done already:
"kindly set [xHCI Mode] to [Enable]"

OtheHill,
Do you suggest I do a clean install of Windows before performing the steps you recommended?

NO, not necessary. You just need to get the correct drivers installed. If you remove a device and drivers then reboot, Windows will install a generic driver for that hardware.

That is why I instructed to install the correct driver first.
