NOTE: No need to install drivers for following:
Linux Kernel 2.4.10 and above already includes built-in drivers for PL-2303H.
Linux Kernel 2.4.31 and above already includes built-in drivers for PL-2303H, PL-2303XA/HXA and PL-2303HXD.
NOTE: Google Android OS is also based on Linux kernel so it also supports PL2303.
