UASP under W7 dependent only on chipset/drivers?

Basically, what I would like to know is: Can Windows7 support UASP?

While doing research for a new USB 3.0 External HD enclosure, I found out about UASP. I understand that both ends must support UASP in order for it to work.

I.E. the USB3.0 controller on the motherboard or PCI-E card must support UASP AND whatever device you're plugging into it, like an ext HD must also support UASP.

Does UASP also depend on the operating system? I know Windows7 does not NATIVELY support UASP, but I DO NOT KNOW if that matters or not, b/c the chipsets of the USB3.0 controllers (and their drivers) are what determine UASP support.

I found this article saying "W7 UASP support might come out after Windows8", but the article is roughly 18 months old. http://www.tomshardware.com/reviews/usb-3-uas-turbo,3215-4.html

Yes, it can work in Windows if you have the proper USB controller and driver. For example, ASUS supports it on the ASM1042 controller, branding it as "Turbo" mode.

Thanks, mfenn. I am planning on buying a USB3.0 UASP-enabled PCI-E card to put in my NAS/file server and a UASP-enabled Ext HD enclosure....both from the same manufacturer, just to be safe.

I did a cursory such for a Windows Update explicitly to support UASP...didn't find anything.

I don't think you're going to find one for Windows 7. MS has a habit of not supporting new protocols in an older OS in order to encourage upgrades. A manufacturer of PCIe (or otherwise) USB 3.0 controllers is of course free to implement UASP in their own driver.
