I'll try that when I get home tongiht and see what happens. The two machines are of different archecture (the AMD is a Core2 Quad and the i386 is a Intel single core). I'll try bouncing both machines between the USB1 and USB2 stack and see if I can get a more detailed report. I have also built some PCB's based around the FTDI chip for an embedded project I did, so I can give you a report on those as well. Im not sure what the Prolific adapters use.. Peg
