libusb_open_device_with_vid_pid libusb 1.0.9 Segmentation fault: 11

[thireus]

Hi there,

With the latest version on MacOS 10.7.4 libusb 1.0.9 using libusb_open_device_with_vid_pid function causes Segmentation fault.

I do not have any other log file to provide. With libusb 1.0.8 everything is ok with this function.

Regards,
Thi.

Please provide the log and more details. If not, it is very difficult for people to help you.

Are you aware of configure parameter --enable-debug-log ?

If you would rather not touch your system installation of libusb, you do not have to. This is how I made lsusb use a local version of libusb 1.0.9 with debug logging enabled:

wget http://downloads.sourceforge.net/project/libusb/libusb-1.0/libusb-1.0.9/libusb-1.0.9.tar.bz2
tar xf libusb-1.0.9.tar.bz2
cd libusb-1.0.9
./configure --enable-debug-log --prefix="$PWD/usr"
make
make install

LD_LIBRARY_PATH="$PWD/usr/lib" /usr/bin/lsusb

I need some for of log or backtrace to figure out why this might be happening. If I don't get anything I will have to close this ticket *(you can reopen if the problem occurs with 1.0.16).

BTW, on OSX he needs to set DYLD_LIBRARY_PATH.

I am closing this ticket due to lack of info. Please try 1.0.16 when it is released and reopen this ticket if the segmentation fault still occurs.
