You're correct to want to do this eventually. But when you're first starting out, it only complicates things. Until you get things working, you might want to consider something higher. But there's nothing wrong with leaving it as you have it, just that it might make things more challenging. >> numBytesToRead = 20;//ftdic.readbuffer_remaining; Yea, ftdic.readbuffer_remaining is not going to help you here. That indicates how much extra libftdi read from libusb but didn't return to you. That will sometimes be zero, which, in this case, would cause you to never get new data from the usb bus into libftdi. (I'm going to ignore the very large block of commented-out code.) I don't see anything particularly wrong with the setup. I would usually check the return value to see if it equals how much I sent, but perhaps that's overkill. You're probably ok.
