I can't help much, but in case you need to try something different,
consider trying rotctl (hamlib) to manually send commands to the LVB
tracker. This way you can at least be sure that it's not a computer issue
(although it doesn't appear that that is possible).
The only other thing I can tell you is that neither of the meters on my
G5400B controller work (one is never even remotely close to the actual
position, and the other doesnt move at all) - yet the value displayed on my
Fox Delta ST2 are always dead on and the rotators track
position perfectly. Good luck!
