Hi everyone, 
	I havent tried this on the i386 box yet (as it takes a few hours to compile 
the world and kernel) but I did some more testing on the AMD64 box. 

	What I have found is:

	AMD64 USB2 on prolific adapter:  BAD
	AMD64 USB1 on prolific adapter: GOOD
	AMD64 USB2 on FTDI adapter: GOOD

	I have included a few text files of the dmesg USB section for debugging with 
the prolific adapter.

	Anything I can do to help, please let me know.. 

Peg
