Package: dfu-util Version: 0.11-3 Severity: normal Dear Maintainer,
This tool intermittently exits with error code 251 after performing a successful update. This occurs because `libusb_reset_device()` returns `LIBUSB_ERROR_NOT_FOUND`, which can happen on some devices. There is a fix available upstream: https://sourceforge.net/p/dfu-util/dfu-util/ci/4800abbf917c7e10db495004b4dfbe366b429867 Upstream has not released a version with this fix in the 3 years since it was committed. I believe debian users could benefit from patching this fix into unstable: commit 4800abbf917c7e10db495004b4dfbe366b429867 Author: Francesco Dolcini <[email protected]> Date: Tue May 23 09:47:08 2023 +0200 main: Return success if final reset fails due to device gone Return with success when libusb_reset_device() returns LIBUSB_ERROR_NOT_FOUND. Without this change 251 (LIBUSB_ERROR_NOT_FOUND = -5) would be returned to the shell.
