When cursor is starting to move uncontrolled? When does it
happen? Once after start, suddenly or ...
Also are You really sure that You can see the cursor? since
cursor is something mouse related (no touch related).
It's difficult to advice something here... You have
to DEBUG your platform in order to find what is really
going on. It looks like you serial driver reports some
dirty touch data. Or may be You drivers are ok, but
serial controller report some dirty data. Or may be problems
with serial connection. Or .... whatever. You have to find a
way to debug You driver.

How many serial ports do You have? If You have two
then use DEBUGMSG/RETAILMS/etc
(through OEMWriteDebugString) to print some debug
info to second port.
