+@deffn {Config Command} {ft2232_channel} number
+The FTDI FT2232 chips have more than one serializers. Some JTAG cables doesn't
use
+the default channel (1). You can change the channel using this option. Valida
values
+range from 0 (automatic) to 4. This is useful when you have a cable that uses
a known
+layout, but a different channel (i.e. Opendous FT2232 cable is like jtagkey
but using
+channel 2 instead of 1).
