I am attaching image of BT Stack software (look on bottom right). I got 7.10.10(T).
I am also including screen shot of my 'Device Manager' showing that i do have a Dell 350.
Hope this helps in finding cause of the issue and...
it shows (on the icon in bottom right) that it is an evaluation version for 30 days. Has anyone seen this and/or know how to fix this.
By the way, new Toshiba stack is working beautifully for windows 7 (with lot more functionality).
