Windows Vista does not recognize the U disk solution

Since I installed my Windows XP upgrade to Windows Vista, I found that my innovative SoundBlaster live 5.1 and U disk have become unrecognized devices. After downloading the KX driver on the Internet, the problem of the sound card is solved, but the problem of the U disk is not solved, and naturally, the ReadyBoost technology cannot be used.

I finally got the solution today. When inserting a USB flash drive, or if you find an unknown device from the device manager, right-click and select "Update Driver". When prompted to "Automatically search for updated driver software" and "Browse for computer to find driver software", select "Browse Computer". To find the driver software, fill in the C:\\Windows\\System32\\DriverStore\\FileRepository

in the driver location that is prompted next, and then Vista will install the U disk driver.

I think the reason for this problem is probably because I upgraded from XP, not to the newly installed Vista. As a result, the U disk drivers are different. As a result, Vista is installed. After that, the U disk became an unrecognized device.

Now that the U disk is ready to use, just try ReadyBoost. My memory is 1G, U disk is 512M, select the removable disk, select "Properties" in the right-click menu, open the "ReadyBoost" tab, select "Use this device", the system recommends 440M allocated to memory usage.

Then update the Windows Experience Index basic score, I found a strange thing, the memory score 4.2 has not changed, but my 64M Nvidia 5200 graphics card score has improved, the lowest game graphics score increased from 2.0 Is it strange to be 2.6?
