I had libusb 0.1.7 installed, but libgphoto was ignoring my USB camera (was previously working, broke on upgrade somewhere along the way). I noticed deep in the ./configure step of libgphoto2_port (now an internal part of libgphoto2) that it complained that libusb was insufficiently modern. Upgraded libusb to 0.1.8 and the libgphoto2_port part picked up USB fine. Recommend DEPENDS >=libusb-0.1.8 AfC Sydney Happy New Year
fixed in the latest versions in ~x86. thanks for your report.
