Click "Start" button, type "devmgmt.msc" (without quotation marks) in the "Search" bar and press "Enter". Click "Continue" if necessary.

In Device Manager, double click to expand "Universal Serial Bus controllers", right click on the Host Controller, click "Uninstall" and click "OK".

Repeat the step 2 to uninstall all items under "Universal Serial Bus controllers".

Then, restart your computer and Windows 7 will reinstall all USB controllers automatically.

The most common reason is that your data on it lost.

Hello, the problem is that your data on the USB flash drive hhas lost so your PC can not recognize it. You can use recovery tool to restore your data. Such as 4Card Recovery, which is very strong recovery software. Pay attention to it, do not cover your old data by new things.
