      Fix mem leak with libusb by introducing buses/usbbus.c · 9dcf7378
      Philippe Teuwen authored
      Now call only once usb_init(); usb_find_busses(); usb_find_devices()
      instead of multiple calls in several scan() then open()
      
      This fixes the following leaks:
      
      ==1159== 8 bytes in 1 blocks are definitely lost in loss record 9 of 102
      ==1159==    at 0x4C28BED: malloc (vg_replace_malloc.c:263)
      ==1159==    by 0x53D9931: usb_parse_configuration (in /lib/x86_64-linux-gnu/libusb-0.1.so.4.4.4)
      ==1159==    by 0x53DB8B1: usb_os_find_devices (in /lib/x86_64-linux-gnu/libusb-0.1.so.4.4.4)
