I understand what you are saying, and would agree if I were using Windows or Mac. I am pretty confident it is not a problem on my computer end...Linux does not use "drivers" the way Windows and Macs do - everything going out a USB port in Linux goes out using the dialout device, /dev/tty. When the user is a member of the dialout group, and there is an FTDI or Prolific (even counterfeit) chip on the other end, a /dev/ttyUSB0 device is created, which is then made read/write with chmod. Linux is remarkably un-fussy about what the chip is. Whatever the chip in the Raduino is, it does not seem my computer is not having a problem with it.

Whatever the chip is in the Raduino is, /dev/tty is? recognizing it and creating the USB device on? the computer. The IDE knows the USB device is there, and I am making it read/write, which has always worked for everything else.

Thanks for the input though. I think I may j just set this aside for a while and come back to it later.
