Umm, there is a Labview unit supplied in the zip file of this particular USB-GPIB project. So my thinking was to make the PIC hardware as compatible to the project as possible to minimise playing with the drivers. It sounds like this may all be a non-problem, from what others have said about the FTDI chip. I must admit that I had only skim read the article, and not digested it deeply. I think I am going to have to dig deeper and get some sample chips. Anyone know of an alternative to the 75160/75161 GPIB Bus Driver chips? They do seem to chew a heap of current. They also seem to be on notice as going out of production with "last buy" notices at TI and I think I found "not available" at National Semiconductor. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
