Currently the following programmers support this mechanism:
.BR nic3com ,
.BR satasii .
.sp
The ft2232spi has an optional parameter specifying the controller type and
interface/port it should support. For that you have to use the
.B "flashrom -p ft2232spi=model,port=interface"
syntax where
.B model
can be any of
.B 2232H 4232H
and
.B interface
can be any of
.B A
.BR B .
The default model is
.B 4232H
and the default interface is
.BR B .
