Windows 7: USB not working after policy changes (Windows 7)

USB not working after policy changes (Windows 7)

USB detail: Lexer 32GB

The cause of the problem or what I think it might be the cause:
I noticed that the transferring rate is very slow from my PC to the USB, so I change the policy setting for that USB drive to be more optimistic (I think the actual option is called cache something something with a check box) using Device Manager. However, the Lexar USB properties setting crashed while I was changing the USB policy. First I tried to stop the properties setting by using task manager, but that didn't work, so I unplugged the USB from the port and the entire DM and the properties setting close itself. However, now whenever I plug in that USB, it didn't work anymore.

To be more specific as to what happens when I plugged in that USB now. The light in the USB will always be on at all time. Not showing up in my computer nor auto running. Shows up in DM with message saying 'this device works properly', but when I go look at the capacity information, it display nothing, also tries updating the drive and uninstalling it while I was in DM, but always seem to be stuck. Tries to find it in Disk Manager, but couldn't find anything about a 32GB drive.

I have tried the following:
1. Plugging other USB mass storage device = works
2. Plugging that Lexer in another PC = works

So my conclusion is that my PC reads other USB mass storage drive, but not this Lexer one. What can I do so that I can use my Lexer USB again?

Group Policy Editor or Local Security Policy
Will either of these allow me to restrict drive access to a single user only? I've tried to restrict drive access with Group Policy Editor but it applies the restriction globally--even to me the administrator. Could anyone let me know if this is possible and how to do it? Much thanks.
