I think the reason your seeing Dell is because the disk I used to load windows 7 HP was an oem disk I purchased from trinity software. As you mentioned, the PC pc when purchased, was loaded with Vista.

Actually, the Dell is just one of the manufacturers using that Renesas controller,

Code:
0x0194	
Chip Number:	0C0330
Chip Description:	NEC USB 3.0 Host Controller Driver || Renesas Electronics USB 3.0 Host Controller
Notes:	Ver. 2.1.39.0 (2015-06-19) - http://downloads.dell.com/FOLDER01557883M/1/Chipset_Driver_X2NF0_WN_2.1.39.0_A03.EXE || http://global-download.packardbell.com/GDFiles/Driver/USB/USB_NEC_2.0.26.0_W7x64_A.zip?acerid=634310869656737277&Step1=NOTEBOOK&Step2=EASYNOTE&Step3=EN%20TS44HR&OS=711&LC=es&BC=PACKARD%20BELL&SC=EMEA_11P - the device is further used in Sony Vaio laptop modles VPCF1. - The libusb developers found older drivers to be corrupting the port number.
Packard Bell, Acer and Sony also are listed.

That site goes by the Hardware ID's and Vendor ID's, that stuff above is what they list for drivers.

Those ones I listed above are chipset drivers for the USB3 controller.

If you want to try it, I'll post the Dell supplied driver. It automatically downloads if you highlight the full link and search,

Code:
http://downloads.dell.com/FOLDER01557883M/1/Chipset_Driver_X2NF0_WN_2.1.39.0_A03.EXE
I've had to do that before on laptops where the original manufacturer didn't supply drivers anymore.

I opened up the installer and checked the vendor/hardware numbers which match with what you posted.

Just so you understand what that site is, it uses the numbers in the hardware ID's to locate known drivers,

I used 1033 as your vendor, and 0194 as the device,

It then shows available drivers based on those numbers, and Dell is the only one actually able to download.

If you want to try it you can put those numbers in just to see how it works,

Will this driver load itself? and is there a chance it can screw anything up after loading the driver?

Is this it?

Or did you already list the link above?

It is an .exe so it will run an installer, I would use it on my computer but that's me.

If you're not sure about it or don't feel good, you certainly shouldn't try it.

If everything is working, you may not want to bother with it.

I was just trying to help clear up that symbol.

Feel free to wait for others advice as well.

That's always a good idea. Backup and sleep on it.

You're welcome.

N2Abyss, some PC manufactures disable AHCI if they're using a custom/oem motherboard.

My old Dell PC board was based on an Intel P965 chipset which was AHCI capable but Dell removed AHCI in the BIOS (you could also see this when booting up, it would say "AHCI BIOS not installed").

It did have the option "RAID ON" and I was told that this would be okay for an SSD as it was using the IAStor (Intel Raid) drivers because I had 2 HDD's setup as RAID0
