[Libusb-win32-devel] Marking libusbk as unmaintained

[Xiaofan C. <xia...@gm...>]

Hi all,

FYI I have marked libusbk as unmaintained as Travis is no longer
active in maintaining the project.

Ref:
https://github.com/mcuee/libusbk

Status: unmaintained and with limited support as lack of developers
to take over
