Linux Kernel 2.4.31 and above already includes built-in PL2303 drivers for our USB Cablet Set. Due to Linux having many versions, we are unable test on all of them, but it should work. We have tested it on our computer using Fedora 11 Kernel 22.214.171.124 & Ubuntu 10.04 LTS using the command in Terminal:
stty -F /dev/ttyUSB0 ispeed 4800 && cat < /dev/ttyUSB0
The RS232 cablet set doesn't need any drivers.
