[Nut-upsuser] LibUSB-1.0+0.1 testing wanted, NUT 2.7.5 pending

[Yogesh Bhanu]

Hi Jim,
FWIW, the new version works with libusb and libusb-compat.

On Arch linux, I can install both libusb packages in parallel.

--snip--
[alarm at 3pi network-ups-tools-git]$ pacman -Ss libusb
core/libusb 1.0.24-2 [installed]
    Library that provides generic access to USB devices
extra/libgusb 0.3.8-1
    GObject wrapper for libusb1
extra/libusb-compat 0.1.7-1 [installed]
    Library to enable user space application programs to communicate with
USB devices
--snip--

+ I  modified the PKGBUILD to reflect the changes.

--snip--
[alarm at 3pi network-ups-tools-git]$ git diff PKGBUILD
diff --git a/PKGBUILD b/PKGBUILD
