Zen Vision not found in Explorer?

I had to reinstall my XP and found my Zen Vision M was not recognized to be connected in the creative source explorer. Even though the USB was working. Here is the solution: Go to the Control Panel and double click on the System. Click the Hardward tab and click on the Device manager. Probably the player is either listed under Unknown or some place mismatched. Right click on it and go to its properties. In the details, select the Hardware Ids. Note the first line and find the number (strip all the characters and symbols). Open the Windows registry (Run regedit). Go to HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet -> UsbFlags and delete the key(s) matching that number. Connect the device again and look at the device manager. If you see the device under the Portable Devices with an yellow exclamation mark, double click it and select to reinstall the driver. That should fix it.
