qwerik , try these few steps to modify the ADFU file:

In the screen shot you attached above, Right Click on the USB Device and select Properties. A new window should now appear.

Select the Details tab and in the drop down menu, select Device Instance Id.

Look for a line that begins with something like this:
USB\VID_10D6&PID_xxxx .....

Note down the 4 characters denoted by the xxxx. For my case, it is 1100, it might be same or different for you.

Now open the ADFUupdate.inf file with notepad. Look for the section beginning with [upgrade]. Add the following below it:

%USB\VID_10D6&PID_xxxx.DeviceDesc%=MDisk.install,U SB\VID_10D6&PID_xxxx

Note that you'll need to enter the 4 characters you located earlier on into this line. Replace the 4x with the number you recorded, there are 2 of these to replace.

Now look for the [Version] section, and locate this line:

;ClassGUID=1181f4a0-f284-11d2-9068-00609797ea5a}

The numbers maybe different from mine, but the steps are the same.
Remove the semi-colon " ; " from the beginning, and add an open bracket " { " at the beginning of the numbers. So you should edit it to something like this:

ClassGUID={1181f4a0-f284-11d2-9068-00609797ea5a}

Finally save the new ADFUupdate.inf file, and try installing your player using this newly edited file.
