Re: [Qemu-devel] [PATCH 4/4] usb-host: raise libusbx minimum version to 1.0.13

[Ed Maste]

I recently discovered QEMU's libusb support and hoped that this would
provide a good solution for the USB host issue on current FreeBSD
versions.  (Right now the FreeBSD ports tree sets USB_HOST=stub, since
the bsd USB code isn't compatible with FreeBSD 8.x and later.)

I'm wondering how best to address QEMU's libusb support on FreeBSD,
and discovered the libusb vs. libusbx saga.  Is it safe to assume that
in the Linux world "pkg-config libusb-1.0" is generally going to refer
to libusbx?

FreeBSD has its own libusb-compatible implementation, but currently
lacks libusb_get_port_path and perhaps others, and if libusbx is
virtually universal on Linux we presumably want to grow these same
interfaces.
