Hi got this feature request: https://bugs.archlinux.org/task/29999

- fedora ditched the libusb usage in favour of the libusbx project.

http://www.libusbx.org

Shall we move to this too?

Questions not answered in the bug report: 1) What is an actual issue solved by libusbx that is present in libusb? (by Allan) 2) Is it a drop-in replacement that is API-compatible or (better) ABI-compatible.

ad 1) I guess there are such issues, otherwise the libusbx people wouldn't have been angry enough to make a fork. This point requires research.

From what I gathered, the difference is currently minimal as the libusb maintainer backported most of the commits from libusbx. I assume this can not go on forever though...

...

ad 2) If it is ABI-compatible, there is no harm in switching right now, as libusbx = libusb-1 + active development + more bugfixes. If it is only API-compatible or partially incompatible, we would need a strong reason to actually switch.

It was advertised as a drop in replacement, I assumed this means ABI compatible, but this we must check.

What about libusb-0.1/libusb-compat compatibility? Quick check in core packages shows it as dependancy for some packages. Regards,
