I have a USB-to-serial adapter on one of the USB ports connected to a serial
port Wacom tablet. The Wacom is controlled via TabletMagic (opensource
project) preference pane. The pane initiates a daemon when required (the user
can enable & disable the daemon from within the pane).

All was well until I tried installing a Wacom driver (there are no modern
drivers for serial port tablets, but where's the fun in not experimenting?).

Once I determined that the Wacom s/w didn't work I uninstalled everything I
could find (a few files in Extensions and Application Support folders) that
had names related to Wacom or Tablet. (There is nothing other than the pref
pane associated with TabletMagic so there is no danger of getting too
delete-happy...)

The tablet now doesn't work as it used to -- sometimes it is not recognized
by the pref pane, sometimes it is but no data transfer takes place.

I plugged a loop-back adapter to the USB-serial adapter and launched
QuickTerm. (QT settings: 9600, 8/1/none & no handshaking.) The resulting text
on the screen is good from between 160-250 characters. Then lock-up. Or
outright crash.

Any suggestion as to my next step would be greatly appreciated.

Thanks,
Dave

I have 2 of the USB-serial adapters. Swapping the adapters doesn't change the
symptoms.

Thanks,

Permissions repair and PRAM reset, no joy.

Try another USB port? Spit on the connectors? Complete backup restore?
Maybe not worth it......

Anything serial port is ancient, and Wacoms aren't that expensive unless
you're into the commercial sized ones.

My condolences. The day I threw mine into the box in the closet was a
good day for me.
