Not able to get Steam to install Steam Controller driver

[HAXTC]

I can not for the life of me get Steam to trigger the driver installation for the Steam Controller.

I've went through the troubleshooting guide than can be found via the pinned discussion thread for known issues a few times. I've also found a thread on steampowered in which some people suggested checking device manager and trying to manually install a driver that would maybe trigger Steam to recognize the controller. I've been at it for a day and a half now with no succes.

I've also tried connecting the controller to my girlfriend's PC and there Steam immediately recognized the controller. I then updated the controller's firmware hoping it would fix the issue at my setup but unfortunately it still didn't recognize it.

I did notice that a few people in the thread say it comes up in device manager as multiple devices. For me it does not. When I connect it wirellesly it shows up in 'Other Devices' as "Steam Controller". When I connect it with the included cable it shows as "Wired Controller".

I've also tried reïnstalling Steam multiple times. In both cases I also checked and deleted all registry entries I could find and double checked nothing was left in my D:/ partition (that's where I install Steam, including games) and in the Appdata folder.

And I've also disabled all Anti-Virus, Anti-Malware and Firewall programs just in case something could be blocking Steam to recognize the controller.

I am at the end of my game here.

My specifications:

Windows 7 Ultimate x64
AMD FX-8350
Asus Crosshair V Formula-Z
2 x Asus R9 290
RAM 16GB

Note that my girlfriend runs the exact same Windows and has the exact same updates and programs installed as I do (I always perform all installations and maintenance on her PC as well).
And besides it reasonably working with Steam Link it shows firmware version as 0x0000000 and dated from 1970, no matter which computer I stream through Steam Link.

Btw I've already sent a ticket to Steam Support yesterday but I fear it might take a while before I'll get a response.

Any help would be greatly appreciated.

Thanks to this thread, and a post by Jean-Luc Picard, I finally knew where to look;

I opened C:\Windows\inf and wasn't able to find a file called 'usb.inf', just a few which names were the same except for an added word like; 'usbcir.inf', 'usbport.inf' & 'usbprint.inf', etc... That's when I realized 'usb.inf' might be the file my Windows setup was missing (at least in my case) and that could be the reason Steam wasn't triggered to install the correct driver.

I went to C:\Windows\inf on my girlfriend's setup (on which my controller actually did work from the start for some reason) and there was an usb.inf and another one called usb.pnf. I copied the files to a stick and moved them to my \Windows\inf directory, rebooted and let Windows search for drivers via Device Manager (wired and wireless, one after another) and it instantly found them and Steam recognized the controller. So far everything works like it should and I haven't edited anything except copying some files. So those who are able to successfully connect their controller on another setup could probably just as easy copy the files from that setup to their own one.
