Author: kevans Date: Tue Jun 16 12:21:55 2020 New Revision: 362224 URL: https://svnweb.freebsd.org/changeset/base/362224 Log: MFC r361977: libusb: improve compatibility Specifically, add LIBUSB_CLASS_PHYSICAL and the libusb_has_capability API. Descriptions and functionality for these derived from the documentation at [0]. The current set of capabilities are all supported by libusb. These were detected as missing after updating net/freerdp to 2.1.1, which attempted to use both.
