[sane-devel] OS X and umax 1220u

[David Minor]

Using the new version of libusb that Mattias Ellert packaged with his 
twain interface, OS X 10.3 is responding much friendlier towards the 
1220u.  Unfortunately, it still doesn't scan.  However, it first sees 
the scanner and reports that it knows what it is, then when you try to 
scan, it complains about an Invalid argument.  The output of scanimage 
with SANE_DEBUG_UMAX1220U=128 is below.  Any ideas on why it is dumping 
or what I might try?

Thanks,
dm
