  Heya
 
 Thanks for the reply, I'm using the latest version 1.2 for windows and I
 use this programmer with other softwares with that same dll and it works
 fine on both ports
 
 But in case I tried with the old libftdi 0.18 and it's the same error
Sorry, I'm just poking in the dark. Another idea: Some other driver or
program might have claimed access to port B and is blocking it. flash-
rom doesn't know how to handle that, maybe your "other softwares" do.

  Hello,

 I got flashrom compiled for windows and it works like a charm (has to
 tweet the code a little, add data for the chips i want to work with, add
 4BA and fast rading for FT2232), it works perfectly fine but only for
 the port A (flashrom -p ft2232_spi:type=2232H,port=A)

 Using default programmer "ft2232_spi" with arguments
"type=2232H,port=A".
 Calibrating delay loop... OK.
 Found Macronix flash chip "flashrom -p
 ft2232_spi:type=2232H,port=AMX25L25665E" (32768 kB, SPI)
 on ft2232_spi.
 Reading flash... (0% to done.)

 If i use the port B (flashrom -p ft2232_spi:type=2232H,port=B), i get
 this error

 Calibrating delay loop... OK.
 Unable to reset FTDI device (USB device unavailable).
 Unable to set latency timer (USB device unavailable).
 Unable to set bitmode to SPI (USB device unavailable).
 ftdi_write_data: -666, USB device unavailable
 Error: Programmer initialization failed.

 I get this error also if i try to compile with make
 CONFIG_DEFAULT_PROGRAMMER=PROGRAMMER_FT2232_SPI
 CONFIG_DEFAULT_PROGRAMMER_ARGS="type=2232H,port=B" to force port B

 I looked around i didn't find any solution to fix this, anyone could
 give me a hand?
 the problem probably lies within your (windows) version of libftdi. I'd
 try another OS / libftdi to rule that out.
