Hi Robert,
Once initiated, you can't revert the activation request. Your existing key
is all you need, there is no need to obtain another one. A single change of
hardware wouldn't normally trigger this, but multiple changes add up and
can.
Theoretically, you can chain up to 127 USB devices, but you'd need to add
some powered terminals for that.
