I don't think a standard cp2102 adapter works with prisma boards. I have a few ASICMINER adapters left over, and I think sidehack/novak still have some of their custom made adapters available.
i guess firstly i need to check the boards to see if they do have numbers written on the top right of them, are they any other identifying features i should be looking for ?
ill get the screwdriver out and take some pics of a board later today.
if ,and at this point its a big if, they are prisma boards how much would you want for a correct adapter ?
thanks
