Not to forget this, did you ever try the CVS version?

You can download and make the driver with:
cvs -z3 -dserver:[email protected]:/cvsroot/zc0302 co -P zc030x
cd zc030x
su
make
Not sure if make install is needed?
Then try loading with something like:
insmod zc030x.ko debug=N

where N = 0, 1, 2, 3, 4 or 5

0 = no debug messages
1 = init/detection/unload and other significant messages
2 = some warning messages
3 = config/control function calls
4 = most function calls and data parsing messages
5 = highly repetitive mesgs

Their homepage seems not to be working: http://zc0302.sourceforge.net/zc0302.php
The buglisting is not very promising: http://sourceforge.net/tracker/?atid...49&func=browse
