Hi!

The ark3116 looks like not to be compatible with the pl2303.
I found a very basic driver for the ark3116 here:
http://www.linuxquestions.org/questions/showthread.php?p=2184457#post2184457

Based on this version i wrote a driver for the ark3116 which supports
baud rate selection, data bit count, parity and stopbit selection.
I got the setings running usbsnoopy while using the ark3116 under my windows box.

I tested the different baudrates and 6N1,7N1,8N1 with external hardware.
75 and 460800 baud (and higher baudrates) are currently not supported.

The driver is still very experimental...
If it is working for you please send me an email

I am not reading the list so please make sure to add my emailadress as
CC (ark3116_linusb_list@auctionant.de)

The driver can be found here:
