Now I know the reason, because there is no libusb-1.0.so.* under
Freebsd 8/9. libusb.so (point to libusb.so.2) is both for libusb 0.1
wrapper and the libusb 1.0 wrapper.
[mc...@myfreebsd ~]$ ls -la /usr/lib/libusb*
-r--r--r-- 1 root wheel 64434 Apr 4 16:04 /usr/lib/libusb.a
lrwxr-xr-x 1 root wheel 11 Apr 4 16:04 /usr/lib/libusb.so -> libusb.so.2
-r--r--r-- 1 root wheel 52968 Apr 4 16:04 /usr/lib/libusb.so.2
-r--r--r-- 1 root wheel 68340 Apr 4 16:04 /usr/lib/libusb_p.a
-r--r--r-- 1 root wheel 11926 Nov 21 22:54 /usr/lib/libusbhid.a
lrwxr-xr-x 1 root wheel 14 Nov 21 22:54 /usr/lib/libusbhid.so ->
libusbhid.so.4
-r--r--r-- 1 root wheel 11400 Nov 21 22:54 /usr/lib/libusbhid.so.4
So I further changed libusb10.py. With the following changes,
it goes further. Still it could not find the test device even though
lsusb shows the device is there.
def _load_library():
if sys.platform == 'win32':
libname = ctypes.util.find_library('libusb-1.0')
elif sys.platform == 'freebsd8' or sys.platform == 'freebsd9':
libname = ctypes.util.find_library('usb')
else:
libname = ctypes.util.find_library('usb-1.0')
if libname is None:
raise OSError('USB library could not be found')
return CDLL(libname)
