USB 3.0 ports not working on Gateway SX2370

USB 3.0 ports not working BUT 2.0 ports work ok on Gateway SX2370. Am running Win 7 -64 bit Home Premium. Do not have orig install or repair disks. Bought used with jury-rigged hard-drive and 32 bit operating system. Installed win 7 -64 on new hard-drive and updated to latest BIOS. USB is enabled on BIOS. When I run Windows Device Manager for the USB controllers, my AMD PCI to USB Open Host Controller Device status reads: "This device cannot start. (Code 10)". Also, OTHER DEVICES has no drivers for the Ethernet Controller, USB Controller, and Unknown Device and when I attempt a driver update, it cannot find drivers on my machine or on the internet. GATEWAY does not have any downloadable drivers on their current website when I look up this particular machine on their official website. I DO, however, have a similar machine with the same motherboard, video card, and OS that works, at my disposal. Any suggestions as to where to start, short of making it my new back-porch footrest, would be appreciated. Thanks

Also ran AMD driver Autodetect and it says I have the latest drivers installed for the graphics hardware : 0x1002 - 0x964A PCIE

Did you try this:

Hi there .. Try the Link below .. There are Drivers available for your Ethernet Controller and you need the Chipset Driver ..

Gateway Support - Downloads & Support Documents - Desktop / SX Series / SX2370

I think you may need the AMD USB 3.0 host controller driver ...

Most welcome glad you got it sorted

Hi ... Welcome to Seven Forums .... Try the Windows 8 64 Drivers ...
