Please also refer to the output of eeprom example documented here about my two USB to Serial Converter. Both will load the VCP driver by default. http://developer.intra2net.com/git/?p=libftdi;a=blob;f=README.build The first one is using FT232BM, the second one is using FT232R. Take note the above is not true for FT2232H. Here is the output of eeprom example for my Amontec JTAGkey-2 debugger. It does not load the VCP driver for both CH A and CH B. mymacmini:examples xiaofanc$ ./eeprom -v 0x0403 -p 0xcff8 Chip type 4 ftdi_eeprom_size: 256 0x000: 01 00 03 04 f8 cf 00 02 80 32 08 00 01 00 9a 10 ........ .2...... 0x010: aa 24 ce 12 00 00 00 00 56 00 00 00 00 00 00 00 .$......
