* libusb: implement libusb_hotplug_get_user_dataShengYi Hung2025-07-211-0/+18
| | | | | | | | | | libusb provides a function to get the callback userdata for a given callback since this structure is opaque to libusb user.

* libusb: consider bad fd as a broken eventSHENGYI HUNG2025-06-251-0/+2
| | | | | | | | | | | Application can use libusb_get_pollfds to get pollfds from libusb then close the fd themselves. This cause the hotplug thread unable to leave because it will be consider as a invalid event then loop forever instead of a broken event that should be quit immediately.

* libusb: Emit event after deregistering hotplug handlerSHENGYI HUNG2025-05-081-0/+1
| | | | | | | | | | | | | | | | | | The original implementation did not emit an event when a hotplug handler was deregistered. This omission causes issues for programs that follow the best practices recommended by libusb—particularly those that use `libusb_hotplug_register_callback()` or similar functions in a loop while managing hotplug handlers dynamically. Without emitting an event after deregistration, these programs can become stuck waiting indefinitely for an event that will never come, as the condition to break out of the wait loop is never satisfied.

* libusb: hotplug, use events instead of a timer when possibleBaptiste Daroussin2025-01-161-1/+172
| | | | | | | | | | | | | Try to fetch events from nlsysevent or devd to determine when to scan the usb bus for devices addition or removal. if none are available fallback on the regular timer based (4s) scanner if devd socket or netlink socket is closed or error fallback on the timer based method.

* libusb: fix hotplug sigbusBaptiste Daroussin2025-01-041-9/+12
| | | | | | | | | | | | | | | | | When a hotplug callback has been registered, and the program using libusb is calling libusb_exit then the thread handler is set to NO_THREAD which result in the variable controlling the loop the be set to 0, it does a last pass through device available without having done a scan, which result in a sigbus after it tried to unregister all the devices. directly break the loop instead and cleanup the list of devices this fixes the tests with LGPLed libusb's hotplugtest program MFC After: 3 days Reviewed by: kevans Differential Revision: https://reviews.freebsd.org/D48298
