Hi ,
If i understood well you see the controler device under windows but not in mixvibes ?
If yes , do you have a logitech webcam ?
-    If yes , you need to delete some key in your windows registry
-    -   do like this :
-    -   open Registry editor (start menu > run > regedit > ok) ;
 Go to the key :
- Code: Select all
 HKEY LOCAL MACHINE/SYSTEM/CurrentControlset/Control/Class/{6BDD1FC6-810F-11DO-BEC7-08002BE2092F} 
Select this key and delete the value 
LowerFiltersthen,
Go to the key :
- Code: Select all
 HKEY LOCAL MACHINE/SYSTEM/CurrentControlset/Control/Class/{6BDD1FC5-810F-11DO-BEC7-08002BE2092F} 
-    -   Select this key and delete the value 
UpperFiltersthe go to the key : 
- Code: Select all
 HKEY LOCAL MACHINE/SYSTEM/CurrentControlset/Control/Class/
Do a right click on it and search... enter value 
LVUSBSTA and click Next.
Everytime you find the value 
LowerFilters (only in sub key Control/Class/) , ( 
LowerFilters with value LVUSBSTA) , delete it. 
Restart your computer and connect your controler and your trouble will be resolve.
I hope it's the problem....
Bye
