The branch stable/13 has been updated by hselasky: URL: https://cgit.FreeBSD.org/src/commit/?id=4340df3418ecea57b5e48dec94ac4b1d4f760aca commit 4340df3418ecea57b5e48dec94ac4b1d4f760aca Author: Hans Petter Selasky <hselasky@FreeBSD.org> AuthorDate: 2022-03-02 11:31:27 +0000 Commit: Hans Petter Selasky <hselasky@FreeBSD.org> CommitDate: 2022-03-05 14:40:08 +0000 libusb(3): Ignore SIGPIPE when initializing the LibUSB v1.0 API. The LibUSB v1.0 emulation layer uses pipes internally to signal between threads. When USB devices are reset, as part of loading firmware, SIGPIPE may happen, and that is expected and should be ignored.
