Makes sense. New cable from KAWAMALL doesn't kill the keyboard/mouse
(X-Windows and the script itself do lock up though). Keyboard/mouse are
still active though so I can at least kill -9 the process and the like. But
still requires a reboot to get the cable working again, so certainly
something bad that the Yaesu is causing to happen with the PL2303 drivers
that the Wouxun doesn't.

Well, I figured it was a script, and I'd just do a diff and see what you
changed and change the VX7 as well. :) Keyspan cable eliminated that need
though.

Saw the other emails, will check and see if you have a new daily build up
with the change. If not, I'll manually make the change and see if it works.
Looks like it should from what submitter said in the other email thread.

Thanks again Dan!
