“Windows Cannot Recognize USB Device”

I am having issues on plugging in my USB device on my Windows Vista PC. The device can be recognized when I plugged it since I can see it in Explorer. However, when creating a folder on the USB flash or save a file, I was unable to do it. When looking at the Explorer, the file which I just saved on my device is not visible. Even the folder which I just created. I tried the USB on another computer and it works perfectly fine. But not on my own PC. How can I fix this?
