DarioG Am not sure where you're sending the data. Or are you receiving them?
I wrote that when I send e.g. Six bytes over USB FIFO to pic micro on the EasyPIC3, first, I see those bytes in the correct order appearing on port C - corresponding LED`s are lighting. But, immediately after those six bytes I see those six bytes again in the same order. Then pic micro stops. The whole process seems to happened twice or to be more precise, it seems that the pic interrupts twice instead of once. (Explanation about how the system works is in attached files; I added the PC application as attachment to my previous post).

FT245R - USB FIFO IC The FT245R is the latest device to be added to FTDI’s range of USB FIFO interface Integrated Circuit Devices. The FT245R is a USB to parallel FIFO interface, with the new FTDIChip-ID™ security dongle feature. In addition, asynchronous and synchronous bit bang interface modes are available.

USB to parallel designs using the FT245R have been further simplified by fully integrating the external EEPROM, clock circuit and USB resistors onto the device. The FT245R adds a new function compared with its predecessors, effectively making it a '2-in-1' chip for some application areas. A unique number (the FTDIChip-ID™) is burnt into the device during manufacture and is readable over USB, thus forming the basis of a security dongle which can be used to protect customer application software from being copied. The FT245R is available in Pb-free (RoHS compliant) compact 28-Lead SSOP and QFN-32 packages. Press releases, articles and web links related to the FT245R can be found. A frequently asked questions page has been created.
