Mtools programs such as mformat and mcopy do not work with the LS-120. On some versions of Unix mtools does work with similar devices such as ZIP drives. Having mtools work with the LS-120 would be a 'nice to have' feature. The work around of mounting the device make the LS-120 useable but having the very handy mtools would be even better.
Will look into the issue - not 7.0, though.
For basic use, take a look at http://swift.embl-heidelberg.de/johnny/sys/ls120-linux.html To integrate such support, we should probably create a symlink in dev (much like /dev/cdrom) - this is a job for kudzu.
