I am testing libftdi.git and somehow the example find_all_pp has segmentation fault problems under Windows, Mac OS X and Linux. I am not so sure if this is a libftdi problem or libusbx problem.
The following is the log under Ubuntu Linux 12.04 x86. BTW, I posted similar messgaes to libftdi mailing list as well. mcuee@Ubuntu1204VM:~/Desktop/build/libftdi/libftdi/build/examples$ ./find_all_pp -v 0x0403 -p 0xcff8 Found devices ( VID: 0x403, PID: 0xcff8 ) ------------------------------------------------ Segmentation fault (core dumped) mcuee@Ubuntu1204VM:~/Desktop/build/libftdi/libftdi/build/examples$ gdb --args ./find_all_pp -v 0x0403 -p 0xcff8 GNU gdb (Ubuntu/Linaro 7.4-2012.04-0ubuntu2) 7.4-2012.04 Copyright (C) 2012 Free Software Foundation, Inc.
