It depends. Do you have any problems with your USB 3.0 right now? If not, don't upgrade. If you do have problems, are you sure it's because of your drivers and not something else? If you have any problems and it's because of the drivers, are you willing to take a chance with a 3rd party site, Station-Drivers.com? Yesterday I used this anti-virus page to check 3 different Station-Drivers.com pages: VirusTotal Anti-Virus check page I used These are the 3 Station-Drivers.com pages I checked with VirusTotal Station-Drivers JMicron page I checked Station-Drivers Marvell page I checked Station-Drivers Renesas page I checked VirusTotal says they are clean. I downloaded 6 files, 3 firmware and 3 drivers. I checked all 6 with Symantec Norton Internet Security. Symantec also says they are clean. Even if the Station-Drivers.com pages are clean, you're still taking a chance on the firmware and the drivers because these files may be written for another machine. From what I understand, a lot of users, at expert level, have used the Station-Drivers.com files with little problems. Ultimately, it's up to you if you want to take a chance or not. If you do apply the firmware and drivers, please post what your results are here.
