Problem with pionner 110d




I have one acard controller with pioneers 110d and recently i upgrade the controler and then i upgrade all my 110d direct from the controler… after that all my 7 x pioneers stop to working. i remove the pioneer and i conect direct to pc and the light not going one and the pc does not detects nothing.
i need to know if there is any change to repair this pioneers, if there is any other soft that i can use to flash or something…
thanks in advance


Which firmware was on the drives and which have you updated with?
