Hello,
What is the problem with those USB fobs? Is it that they are epoxy blobbed?
If they are packaged chips, is it because they are not CM108? What chip are
they? Please post the vendor ID/Product ID info. I have been working with
CM108 compatible chips- maybe I can contribute something useful here.
73,
Andrew
