Grepping the sources, I find this message in (and only in)
module/owlib/src/c/ow_arg.c that is used to build libow.
The sources have:
#if OW_USB
[...]
LEVEL_DEFAULT( "USB library initialization had problems --
can't proceed") ;
[...]
#else /* OW_USB */
(void) arg ;
LEVEL_DEFAULT("USB support (intentionally) not included in compilation.
Check LIBUSB, then reconfigure and recompile.");
return gbBAD;
#endif /* OW_USB */
So, only one of these two messages is compiled into libow.
I downloaded Debian package libow-3.1-0_3.1p0-2_i386.deb and
libow-3.1-1_3.1p1-2_i386.deb,
uncompact them and look at strings into libow.
I only see the first one:
vdanjean@eyak:/tmp/owfs/tmp/usr/lib/i386-linux-gnu$ strings libow-3.1.so.0 |
egrep "USB (library|support)"
USB library could not be initialized -- cannot proceed
USB library initialization had problems -- can't proceed
<%s> Cannot initialize libusb -- USB library for using some bus masters
vdanjean@eyak:/tmp/owfs/tmp/usr/lib/i386-linux-gnu$ strings libow-3.1.so.1 |
egrep "USB (library|support)"
USB library initialization had problems -- can't proceed
<%s> Cannot initialize libusb -- USB library for using some bus masters
And the disassembly of the function where the string occurs (version
3.1p1-2 on amd64) show me that USB is supported.
Can you double checks the version this bug apply? The bug report tells
3.1p0-2 but I cannot find the string you obtain in the binary (and I
find the string that tells that USB is supported)
And can you try with recent the owfs upload? (3.1p1-2) and report if
the bug is still here?
Regards,
Vincent
