>Description:
The configuration step fails with the following log:
===> Configuring for libusb-compat-0.1.7
[...]
checking for LIBUSB_1_0... no
configure: error: Package requirements (libusb-1.0 >= 0.9.1) were not met:

Package 'libusb-1.0', required by 'virtual:world', not found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables LIBUSB_1_0_CFLAGS
and LIBUSB_1_0_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
