Got myself an Acer C710 Chromebook that I hacked/flashed and installed Ubuntu 14.04. TPRT runs fine using WINe, but cant see my AutoProm. Added the COM1 line in dosdevices and tried adjusting the baud speed, no good. Ubuntu sees and identifies the FTDI adapter on /dev/ttyUSB0.

Any ideas? Trying to avoid using VirtualBox due to limited processor power.

did you down load the driver for your auto prom?

You think I need to install an AutoProm specific driver? I figured if it saw the FTDI then it was good to go. Will try that within the next couple days and see if it helps.

Yeah, going to the driver site it indicates that the linux drivers are built into Ubuntu Linux at this point, so it seems to be another problem.

i wrote a datalogging and display suite for linux (its in my sig) but right now its specifically for FTDI devices only.

it does not use the operating system's FTDI driver, in fact you must disable that driver, it uses raw USB protocol to communicate with the ftdi chipset (via libftdi)

it logs to csv, displays to ncurses, and is written in c for ease of plugin development. also has an offline log analyzer for doing wideband afr, blm trim analysis, and knock mapping.

might want to check it out

oh and if you need any graphing capability or manual analysis; you can write scripts for gnuplot to parse your csv logs in bulk....

one more thing if you want to make it work with the linux serial driver post the output of 'lsusb'
