USB-RS232 dongle problems

I am sure we had the driver installed prior to using the dongle. I decided to try prolific chip, since google told me that prolific devices are listed as "Labview compatible" and support all handshake protocols.

You replied into a thread that is a year and a half old with a message that has nothing to do with the thread.

The thread was about getting USB-RS-232 converters to work.  Not about USB security device locks.
