Generally, not many changes are made anymore regarding the core program. Strangely enough, there wasn't the slightest change in the detachDriver() function between 2.5.2 and 2.6.0. So it's likely there is a combination of things happening here. This is the code where the crash is happening: -x-x-x- struct libusb_config_descriptor *config; libusb_get_active_config_descriptor(dev, &config); -x-x-x- So actually the problem is that libusb can't determine and retrieve the active configuration because it can't read the value that would tell it the number/index of the configuration currently set (/sys/bus/usb/devices/1-2/bConfigurationValue). It would be interesting to check if that attribute is actually there. Try # cat /sys/bus/usb/devices/1-2/bConfigurationValue It *might* be that there is some self-switching going on and the device is gone during usb_modeswitch handling it, but that wouldn't explain why the crash doesn't happen with 2.6.0 ... It's obvious though that I need to catch the "get_active_config" function returning an error. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1880191 Title: usb_modeswitch 2.5.2 segfault To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/usb-modeswitch/+bug/1880191/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
