SAM Support?

[cryptoAlgorithm]

I have an arduino due, which in theory should be able to support WebUSB as it has the necessary hardware capability. However it appears that this library only supports AVR or SAMD boards, while my due is a SAM board. What needs to be done to add SAM support? Could it be ported over from SAMD, or does it have to basically be completely remade?

I do not have a solid understand of the inner workings of USB, so excuse my use of non-correct terms/language above :D
