pylon-libusb-1.0.so causing segfault in our application

[mahiuchun]

Describe what you want to implement and what the issue & the steps to reproduce it are:

I noticed that in both pylon and pypylon for Linux, the package contains pylon-libusb-1.0.so which is a build of libusb 1.0.

It's unclear to me which minor version of libusb 1.0 is used or if there is any Basler specific modification

FWIW, libusb 1.0.0 was released in 2008, it's still being updated as 1.0.x, currently at 1.0.26

Currently the presence of pylon-libusb-1.0.so causes segfault in our applications when there are other users of libusb 1.0.

Is your camera operational in Basler pylon viewer on your platform

Yes

Hardware setup & camera model(s) used

x86-64 PC Ubuntu 20.04/22.04

acA2440-35uc USB3

Runtime information:

pypylon: 1.8.0 / 6.3.0.18933

[SMA2016a]

the minor version is 19.

I don't think that this is related to lib usb version. Would you make a GDB trace?

@mahiuchun did you solve the issue?

[mahiuchun]

No I did not. I am trying to create a small program to reproduce; it's going to take a while.

OK. Thanks for the update
