Help in setting up Prolific USB2Serial Adapter in Puppy Lucid 520 needed
 

My USB2serial device was bought used with unknown manufacturer.
Under Windows Vista and Windows 7, I tried the Prolific driver and it worked.
But under Puppy Lucid 520, although the device is seen and I told the application to use USBtty0, and the application says it made a connection, no data is getting transferred either way.

The device is listed with lsusb as Device 14 ID:067b:2303

I would really like to get the device working with my application and am at a loss of what next with puppy.
Also, the manufacturer is shown as Prolific.

I should mention that I followed the instructions from ubuntu to set it up.
Also, the application says a connection was made to ttyUSB0, but no data is being transferred.

I am just unsure how to get that backend driver talking to the emulated serial port so further instructions would be nice.

Further information is from dmesg.
When I activate the connection in aspeqt(a application to interface to an Atari PC), I get a stream of this message from dmesg.
drivers/usb/serial/pl2303.c: pl2303_tiocmget (0)
drivers/usb/serial/pl2303.c: pl2303_tiocmget - result = 6

I do not know what result = 6 signifies.
